Uniform Precession Mode in Spin Wave Resonance

概要

論文の詳細を見る
Excitation of the uniform precession mode of the main peak in spin wave resonance is investigated for perpendicular and parallel cases. A relation between the resonance field for the main peak and the film thickness is examined by using the special films with a constant gradient in thickness. It is found that the resonance curves of these films are very broad and asymmetrical and are composed of the sharp ones of the divided parts having various resonance fields. Since the resonance field for the main peak depends on the film thickness, it is concluded that the uniform precession mode is not excited in thin metal films for both perpendicular and parallel cases.
