Abstract

Ceramics of (1–x)La_0.7Sr_0.3MnO₃/x(GeO₂) and (1–x)La_0.7Sr_0.3MnO₃/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%.
