Abstract:

Magnetic properties of CuCr2Se4 single crystals have been investigated. The saturation magnetic moment at 0 K is 5.07 μ B per formula. The magnetocrystalline anisotropy constants K1 and K2 are -6.9×105 and -0.9×105 erg/cc, respectively, at 5.1 K. In order to examine the effects of annealing on the magnetocrystalline anisotropy, the ferromagnetic resonance at room temperature is measured after annealing in vacuum and in Se-atmosphere, respectively. It is found that the absolute values of K1 and K2 decrease after annealing in vacuum and increase toward the initial values after annealing in Se-atmosphere.
The above results are discussed on the basis of the ionic model.
