SPIN WAVES IN A MAGNETIC SUPERLATTICE WITH SINGLE-ION UNIAXIAL ANISOTROPY
具有单轴各向异性的磁性超晶格中的自旋波

The transfer-matrix method is employed to investigate the spin waves in a magnetic super-lattice with a single-ion uniaxial anisotropy. The dispersion equation of the spin waves is obtained. The effect of anisotropy strength on the spin waves spectrum is also discussed.
