Effects of nanocracks on the magnetic and electrical properties of single crystals
An investigation of the physical properties of La(0.8)Sr(0.2)MnO(3) single crystals grown by the molten zone technique is realized close to the metal-to-insulator transition temperature (T(MI)).

description | An investigation of the physical properties of La(0.8)Sr(0.2)MnO(3) single crystals grown by the molten zone technique is realized close to the metal-to-insulator transition temperature (T(MI)). In this paper, we review the effect of the structural defects through magnetotransport and local magnetic microstructures. From electron microscopy observations, some 'nanocrack' defects (i.e. defects at a nanometer scale) were found, essentially in the center part of the single crystals. At room temperature, magnetic force microscopy measurements have shown that the absence of defects allowed a magnetic ordering of the domains at the crystal edge, which is the best-crystallized region. In addition, the magnetization loops have permitted us to verify that the crystal was ferromagnetically weaker in the center. On analyzing the electrical resistivity data, we observed in the linear current regime a sensitive variation of the resistivity due to defects, by comparing the center and the edge of the material at T(MI). Additionally, at strong current, non-linearity phenomena have been supposed to be related to local heating. Finally, we discuss the structural disorder effect on the relaxation of the ferromagnetic domains. |
