Abstract:
The behavior of the linear and nonlinear dynamic susceptibilities of a ${\rm Nd_{0.77}Ba_{0.23}MnO_{3}}$ single crystal is studied with the aim to verify whether sealing theory is applicable for describing the critical phenomena in manganites with cubic symmetry. The experimental results obtained for the exchange temperature region ($4\pi\chi \ll 1$) agree well with the theoretical predictions, whereas the appearance of magnetically ordered formations in the paramagnetic phase is presumably due to the orbital ordering.
