Concentration anomalies of the magnetization of HgSe:Fe crystals
Abstract The field and temperature dependences of the magnetization of the semimagnetic semiconductor HgSe:Fe have been studied experimentally. The spin splitting of the Landau levels in the de Haas-van Alphen quantum oscillations has been recorded in the iron impurity concentration interval of 7 ×...

| 520 | |a Abstract The field and temperature dependences of the magnetization of the semimagnetic semiconductor HgSe:Fe have been studied experimentally. The spin splitting of the Landau levels in the de Haas-van Alphen quantum oscillations has been recorded in the iron impurity concentration interval of 7 × $ 10^{18} $ $ cm^{−3} $ < NFe < 2 × $ 10^{19} $ $ cm^{−3} $. The effective area of the extreme cross section of the Fermi surface has been determined from the obtained dependences of the oscillation period on the iron concentration, and the concentration of the collectivized electrons under conditions of the stabilization of the Fermi level on the iron donor level has been estimated. The critical impurity concentration at which the sharp increase in the Curie-Weiss temperature occurs owing to the spontaneous spin polarization of the system of hybridized electron states in iron-doped mercury selenide has been determined. | ||

Concentration anomalies of the magnetization of HgSe:Fe crystals |
| abstract |
Abstract The field and temperature dependences of the magnetization of the semimagnetic semiconductor HgSe:Fe have been studied experimentally. The spin splitting of the Landau levels in the de Haas-van Alphen quantum oscillations has been recorded in the iron impurity concentration interval of 7 × $ 10^{18} $ $ cm^{−3} $ < NFe < 2 × $ 10^{19} $ $ cm^{−3} $. The effective area of the extreme cross section of the Fermi surface has been determined from the obtained dependences of the oscillation period on the iron concentration, and the concentration of the collectivized electrons under conditions of the stabilization of the Fermi level on the iron donor level has been estimated. The critical impurity concentration at which the sharp increase in the Curie-Weiss temperature occurs owing to the spontaneous spin polarization of the system of hybridized electron states in iron-doped mercury selenide has been determined. © Pleiades Publishing, Inc. 2014 |
