Abstract

Electron paramagnetic resonance data of La1-xCa xMnO3 compounds with x = 0, 0.1, 0.2, 0.3 were analyzed in order to explore the changes in effective spin-spin interactions and spin dynamics parameters. The presence of two magnetic subsystems - host of superexchange coupled Mn3+ ions and Mn4+ associated clusters is characteristic for x = 0 and 0.1 samples, while ferromagnetically correlated host is observed in x = 0.2 and 0.3 ones. The contributions of both ionic host and doped carriers to spin relaxation parameters were determined using general spin-dynamics theory.
