Abstract:
The electron paramagnetic resonance (EPR) study of La0.6Sr0.2(Ba,Ca)0.2MnO3 manganites was
presented. The temperature dependence of EPR line intensity was described by the Curie-Weiss law. It was
shown that the expression between I(T) and exp(E/kT) based on adiabatic polaron hopping model and Curie-
Weiss law is very closed at high temperature, but near the Curie temperature only the first one is valid.
