摘要：

A Green function formalism is employed to study the effect of nonuniaxial single-ion anisotropy on the magnetic excitations in a dilute ferromagnet. The local density of spin wave states (LDOS) is obtained via diagonalizing the transfer matrix in the Bethe lattice approximation. The dependence of LDOS and the average magnetization on the anisotropy strength is calculated numerically.
