X-band electron magnetic resonance (EMR) spectra were recorded at the temperature range of 115≤T≤600 K on powdered samples of single crystalline La0.9Ca0.1MnO3 and polycrystalline La 0.1Ca0.9MnO3 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.
