摘要：

The characteristic features of the critical spin dynamics of the cubic ferrimagnets Y3Fe5O12 and MnFe2O4 in the exchange temperature region above T(c) have been studied. The magnetic-dipole relaxation of the uniform magnetization of these ferrimagnets is shown to be suppressed. The relaxation channel due to the local uniaxial anisotropy, with a new temperature dependence, is the dominant channel.
