Oxygen pressure annealing enhances the B-site ordering degree of double perovskite $ La_{2} %$ CoMnO_{6} $ ceramics
Abstract The ordering and arrangement of atoms in double perovskite structures play a crucial role in determining their electrical and magnetic properties. In this groundbreaking study, we conducted thermogravimetric-differential scanning calorimetry analysis on the $ La_{2} %$ CoMnO_{6} $ (LCMO) ra...

| 520 | |a Abstract The ordering and arrangement of atoms in double perovskite structures play a crucial role in determining their electrical and magnetic properties. In this groundbreaking study, we conducted thermogravimetric-differential scanning calorimetry analysis on the $ La_{2} %$ CoMnO_{6} $ (LCMO) raw material, shedding light on the remarkable oxygen absorption process that occurs during the phase formation of LCMO. Therefore, LCMO ceramics with double perovskite structure were synthesized by solid-state reaction combined with oxygen pressure annealing (1200 °C/10 h/$ Po_{2} $ = 0.15 MPa). The structure and properties of the samples before and after oxygen pressure annealing (OPA) were characterized using X-ray diffraction with Rietveld refinement fitting, X-ray photoelectron spectroscopy, resistivity, dielectric and magnetic measurements. Subsequently, we thoroughly explored the influence of the degree of B-site (Co/Mn) ordering on the electrical and magnetic properties of the samples. The results show that the $ Co^{2+} $/$ Mn^{4+} $ content of OPA-LCMO is increased, the fraction of the B-site ordering phase ($ P2_{1} $/n) increased by 30%, the magnetization is increased by 7.5 emu/g and the Curie temperature is increased to 216 K with the increase of $ Co^{2+} $–O–$ Mn^{4+} $ arrangement. At the same time, due to the decrease of oxygen vacancy and disordering phase (Pbnm), the carrier mobility of OPA-LCMO is reduced, and the resistivity (T = 300 K) is increased by 20 times. This comprehensive study sheds light on the intricate relationship between OPA, B-site ordering degree, and the resulting magnetic and electrical properties of double perovskite materials. These findings significantly contribute to our understanding and pave the way for the improved design and development of advanced double perovskite materials. | ||

Abstract The ordering and arrangement of atoms in double perovskite structures play a crucial role in determining their electrical and magnetic properties. In this groundbreaking study, we conducted thermogravimetric-differential scanning calorimetry analysis on the $ La_{2} %$ CoMnO_{6} $ (LCMO) raw material, shedding light on the remarkable oxygen absorption process that occurs during the phase formation of LCMO. Therefore, LCMO ceramics with double perovskite structure were synthesized by solid-state reaction combined with oxygen pressure annealing (1200 °C/10 h/$ Po_{2} $ = 0.15 MPa). The structure and properties of the samples before and after oxygen pressure annealing (OPA) were characterized using X-ray diffraction with Rietveld refinement fitting, X-ray photoelectron spectroscopy, resistivity, dielectric and magnetic measurements. Subsequently, we thoroughly explored the influence of the degree of B-site (Co/Mn) ordering on the electrical and magnetic properties of the samples. The results show that the $ Co^{2+} $/$ Mn^{4+} $ content of OPA-LCMO is increased, the fraction of the B-site ordering phase ($ P2_{1} $/n) increased by 30%, the magnetization is increased by 7.5 emu/g and the Curie temperature is increased to 216 K with the increase of $ Co^{2+} $–O–$ Mn^{4+} $ arrangement. At the same time, due to the decrease of oxygen vacancy and disordering phase (Pbnm), the carrier mobility of OPA-LCMO is reduced, and the resistivity (T = 300 K) is increased by 20 times. This comprehensive study sheds light on the intricate relationship between OPA, B-site ordering degree, and the resulting magnetic and electrical properties of double perovskite materials. These findings significantly contribute to our understanding and pave the way for the improved design and development of advanced double perovskite materials.

In this groundbreaking study, we conducted thermogravimetric-differential scanning calorimetry analysis on the $ La_{2} %$ CoMnO_{6} $ (LCMO) raw material, shedding light on the remarkable oxygen absorption process that occurs during the phase formation of LCMO. Therefore, LCMO ceramics with double perovskite structure were synthesized by solid-state reaction combined with oxygen pressure annealing (1200 °C/10 h/$ Po_{2} $ = 0.15 MPa). The structure and properties of the samples before and after oxygen pressure annealing (OPA) were characterized using X-ray diffraction with Rietveld refinement fitting, X-ray photoelectron spectroscopy, resistivity, dielectric and magnetic measurements. Subsequently, we thoroughly explored the influence of the degree of B-site (Co/Mn) ordering on the electrical and magnetic properties of the samples. The results show that the $ Co^{2+} $/$ Mn^{4+} $ content of OPA-LCMO is increased, the fraction of the B-site ordering phase ($ P2_{1} $/n) increased by 30%, the magnetization is increased by 7.5 emu/g and the Curie temperature is increased to 216 K with the increase of $ Co^{2+} $–O–$ Mn^{4+} $ arrangement. At the same time, due to the decrease of oxygen vacancy and disordering phase (Pbnm), the carrier mobility of OPA-LCMO is reduced, and the resistivity (T = 300 K) is increased by 20 times. This comprehensive study sheds light on the intricate relationship between OPA, B-site ordering degree, and the resulting magnetic and electrical properties of double perovskite materials. These findings significantly contribute to our understanding and pave the way for the improved design and development of advanced double perovskite materials.</subfield></datafield><datafield

Abstract The ordering and arrangement of atoms in double perovskite structures play a crucial role in determining their electrical and magnetic properties. In this groundbreaking study, we conducted thermogravimetric-differential scanning calorimetry analysis on the $ La_{2} %$ CoMnO_{6} $ (LCMO) raw material, shedding light on the remarkable oxygen absorption process that occurs during the phase formation of LCMO. Therefore, LCMO ceramics with double perovskite structure were synthesized by solid-state reaction combined with oxygen pressure annealing (1200 °C/10 h/$ Po_{2} $ = 0.15 MPa). The structure and properties of the samples before and after oxygen pressure annealing (OPA) were characterized using X-ray diffraction with Rietveld refinement fitting, X-ray photoelectron spectroscopy, resistivity, dielectric and magnetic measurements. Subsequently, we thoroughly explored the influence of the degree of B-site (Co/Mn) ordering on the electrical and magnetic properties of the samples. The results show that the $ Co^{2+} $/$ Mn^{4+} $ content of OPA-LCMO is increased, the fraction of the B-site ordering phase ($ P2_{1} $/n) increased by 30%, the magnetization is increased by 7.5 emu/g and the Curie temperature is increased to 216 K with the increase of $ Co^{2+} $–O–$ Mn^{4+} $ arrangement. At the same time, due to the decrease of oxygen vacancy and disordering phase (Pbnm), the carrier mobility of OPA-LCMO is reduced, and the resistivity (T = 300 K) is increased by 20 times. This comprehensive study sheds light on the intricate relationship between OPA, B-site ordering degree, and the resulting magnetic and electrical properties of double perovskite materials. These findings significantly contribute to our understanding and pave the way for the improved design and development of advanced double perovskite materials. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023.
