| 摘 要： | A C3Cl-type(bcc)-semi-infinite ferrimagnet with a single-ion uniaxial anisotropy and a magnetic impurity layer is considered through combining Green‘s function theory with the transfer-mairx method.The effect of the anisotropy term and the impurity layer on surface spin wave specirum is discussed.The influence of the impurity layer‘s distance from the surface or surface spin woves is also concerned.

| Abstract: | A C_sCl-type (bcc) semi-infinite ferrimagnet with a single-ion uniaxial anisotropy and a magnetic impurity layer is considered through combining Green's function theory with the transfer-matrix method, The effect of the anisotropy term and the impurity layer on surface spin wave spectrum is discussed, The influence of the impurity layer's distance from the surface on surface spin waves is also concerned. |
