Local magnetic order in manganite thin films studied by 1/f noise measurements
The low-frequency 1/f resistance fluctuations of epitaxial La2/3Ca1/3MnO3 thin films on different substrates have been studied as a function of temperature and applied magnetic field. A film with a high Curie temperature TC=250 K grown on a substrate with perfect lattice match (NdGaO3) shows a low o...

| 520 | |a The low-frequency 1/f resistance fluctuations of epitaxial La2/3Ca1/3MnO3 thin films on different substrates have been studied as a function of temperature and applied magnetic field. A film with a high Curie temperature TC=250 K grown on a substrate with perfect lattice match (NdGaO3) shows a low overall noise amplitude, comparable to that of a conventional metal. In contrast to previous work, no increase of the 1/f resistance noise in the ferromagnetic regime of the La2/3Ca1/3MnO3 film could be observed. The magnitude of the normalized resistance fluctuations decreases with decreasing temperature except for a sharp peak at TC; this peak is completely suppressed by an applied magnetic field of about 2 T. In contrast, the noise level in a film with low Curie temperature (TC=110 K) grown on a substrate (SrTiO3) with large lattice mismatch (1.5%) is several orders of magnitude larger and shows a qualitatively different temperature dependence, with a huge noise increase below TC. These results are discussed in terms of a strong coupling of electric resistance and magnetic ordering, as well as within a percolative picture of the ferromagnetic transition. | ||

Local magnetic order in manganite thin films studied by 1/f noise measurements |
| abstract |
The low-frequency 1/f resistance fluctuations of epitaxial La2/3Ca1/3MnO3 thin films on different substrates have been studied as a function of temperature and applied magnetic field. A film with a high Curie temperature TC=250 K grown on a substrate with perfect lattice match (NdGaO3) shows a low overall noise amplitude, comparable to that of a conventional metal. In contrast to previous work, no increase of the 1/f resistance noise in the ferromagnetic regime of the La2/3Ca1/3MnO3 film could be observed. The magnitude of the normalized resistance fluctuations decreases with decreasing temperature except for a sharp peak at TC; this peak is completely suppressed by an applied magnetic field of about 2 T. In contrast, the noise level in a film with low Curie temperature (TC=110 K) grown on a substrate (SrTiO3) with large lattice mismatch (1.5%) is several orders of magnitude larger and shows a qualitatively different temperature dependence, with a huge noise increase below TC. These results are discussed in terms of a strong coupling of electric resistance and magnetic ordering, as well as within a percolative picture of the ferromagnetic transition. |

The low-frequency 1/f resistance fluctuations of epitaxial La2/3Ca1/3MnO3 thin films on different substrates have been studied as a function of temperature and applied magnetic field. A film with a high Curie temperature TC=250 K grown on a substrate with perfect lattice match (NdGaO3) shows a low overall noise amplitude, comparable to that of a conventional metal. In contrast to previous work, no increase of the 1/f resistance noise in the ferromagnetic regime of the La2/3Ca1/3MnO3 film could be observed. The magnitude of the normalized resistance fluctuations decreases with decreasing temperature except for a sharp peak at TC; this peak is completely suppressed by an applied magnetic field of about 2 T. In contrast, the noise level in a film with low Curie temperature (TC=110 K) grown on a substrate (SrTiO3) with large lattice mismatch (1.5%) is several orders of magnitude larger and shows a qualitatively different temperature dependence, with a huge noise increase below TC. These results are discussed in terms of a strong coupling of electric resistance and magnetic ordering, as well as within a percolative picture of the ferromagnetic transition. |
