Abstract
The behavior of the linear and nonlinear dynamic susceptibilities of a Nd0. 77Ba0.23MnO3 single crystal is studied with the aim to verify whether seali ng theory is applicable for describing the critical phenomena in manganites with cubic symmetry. The experimental results obtained for the exchange te mperature region (4 pi chi << 1) agree well with the theoretical prediction s, whereas the appearance of magnetically ordered formations in the paramag netic phase is presumably due to the orbital ordering.
