摘要：

The Heisenberg exchange interaction model is used to study the bulk and local magnetic excitations of a ferromagnet with a planar defect. A formalism is established to obtain the Green magnetic tensor components, which describe the dynamical response and the dispersion relations in the long wavelength approximation, taking into account the local magnetic field proposed by Phillips-Rosenberg [Rep. Frog. Phys. 29, 285, (1966)] and the semiclassical magnetic torque relation.
