摘要：

The oblique magnetic anisotropy of metal-evaporated tapes for audio recording has been studied by using ferromagnetic resonance techniques at 34 GHz. From the angular dependence of the resonance field (H(r)) in the film plane, the following values of the saturation magnetization (4piM), the intrinsic anisotropy field (H(k)), and the oblique angle of the anisotropy axis from the film normal (alpha) are determined: 4piM = 9.72 kG (9.72 MA m-1), H(k) = 1.03 kOe (82.0 kA m-1), and alpha = 61.5-degrees. Also, the resonance fields in the vertical plane are well fitted except for a few high-field data.
