摘要：
We study here the influence of the surface anisotropy and film thickness on the critical angle βc between the film normal and the direction of the external magnetic field when a uniform mode appears in the spin wave spectrum. We show both analytically and numerically that in any case the uniform mode occurs when the average orientation of the local magnetization subtends an angle αc = 54°7′ with the film normal. © 1979.
