Abstract:
Ferromagnetic resonance (FMR) studies of single-crystal Co1.5Ni0.5SrFe16O27 (Co1.5Ni0.5-W) hexagonal ferrite at 27 GHz have been performed. From the angle dependence of the resonance field in the temperature range of 77-380 K, the thermal behavior of the magnetocrystalline anisotropy constants K1, K2 and K3 has been observed. The regions of spin reorientations and various types of anisotropies related to them have been determined.
