Abstract

Abstract: The Griffiths like phase is probed by the electron spin resonance and AC magnetic susceptibility in the poly- and nanocrystalline mixed valence manganites La0.7 Ca0.3 MnO3 . The novel method to analyze the Griffiths phase allows to determine a quickly decaying temperature variation of magnetic susceptibility of Griffiths phase in a whole interval between the Curie and Griffiths temperatures. A location of Griffiths phase is additionally confirmed by a nonvanishing out-of-phase component of magnetic susceptibility.
