Abstract

X-band electron magnetic resonance (EMR) spectra were recorded at the temperature range of 115≤T≤600 K on powdered samples of single crystalline La_0.9Ca_0.1MnO₃ and polycrystalline La _0.1Ca_0.9MnO₃ manganites, having a mixed magnetic structure in the ground state, which comprises canted antiferromagnetic matrix and nanometer-scale ferromagnetic clusters. A model of the magneto-impurity states for excess holes and electrons, which emerge in the considered compounds due to A-site cation substitution, was used for modeling their paramagnetic susceptibility and spin dynamics measured by means of EMR.
