Заглавие : Magnetoresistivity of La0.7Sr0.3MnO3/Sb2O3 glass composites at room temperature Место публикации : Physics of the Solid State. - 2015. - Vol. 57, № 1. - С. 14-17 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): магнитные поля--релаксация Аннотация: The ceramic composites La0.7Sr0.3MnO3/Sb2O3 with different weight ratios of the components have been synthesized. Their magnetoresistive properties have been studied in weak magnetic fields. The values of negative isotropic magnetoresistance of the 90%La0.7Sr0.3MnO3/10% Sb2O3 composites at room temperature are found to be 1.2% and 14% for 0.25 and 20 kOe, respectively. The observed increase in magnetoresistance with an increase in the field has specific features of the relaxation process. Доп.точки доступа: Kabirov, Yu. V.; Gavrilyachenko, V. G.; Bogatin, A.
