Аннотация
Ceramics of (1–x)La0.7Sr0.3MnO3/x(GeO2) and (1–x)La0.7Sr0.3MnO3/x(Li4P2O7) compositions with x = 0.1–0.3 have been synthesized that possess high absolute values of isotropic negative magnetoresistance MR at room temperature. In a composite containing 20 mass % GeO2 as the barrier component, the negative magnetoresistance reaches MR = 15% in a magnetic field of 18 kOe, while an analogous composite with Li4P2O7 under identical conditions has MR = 16%.
