摘要：
The behavior of the lines of resonant microwave absorption has been studied in a Ho0.4Y2.6Fe5O12 single crystal as the orientation of the external magnetic field was varied in the (110) plane. This plane contains the principal directions of the cubic crystal: [100], [110], and [111]. Experiments were carried out in pulsed magnetic fields up to 250 kOe at liquid-helium temperature at a frequency of 40.5 GHz. A comparison reveals substantial differences between the experimental results and the results of a theoretical analysis based on the model of an Ising ordering of holmium ions.
