摘要：

The Griffiths phase forms in various magnetics in the presence of disorder and spin fluctuations in the system. In this paper, we present experimental facts in which the Griffiths phase is observed from the temperature dependence of magnetization, EPR, and SANS spectra; we present an equation describing the anisotropy fields, which are actually found from the EPR angular dependence of the resonance magnetic field and a formula for determining the critical exponent for magnetizations description. The features of the observation of the Griffiths phase in lanthanum manganites are presented.
