摘要/Abstract

摘要： 研究铁磁/铁磁/反铁磁三层薄膜中应力各向异性场对共振场的影响.得到系统存在声学和光学两种模,并且随着应力场的增强,在某些区域声学模和光学模共振场均向高值方向移动.此外发现声学模共振场对两铁磁层厚度的依赖较大,对光学模而言,随着两铁磁层厚度的改变,应力各向异性场对其共振场的影响甚微.

Abstract: Magnetic properties of ferromagnetic/ferromagnetic/antiferromagnetic trilayers with stress anisotropy are investigated by using ferromagnetic resonance method.Acoustic mode and optical mode are observed.As applied magnetic field in the plane of film.in some regions,with increasing stress anisotropy field resonance fields of acoustic and optical modes shift to higher values.With increasing ferromagnetic film thickness, the shift of acoustic mode resonance field is different. Furthermore.the resonance field of optical mode is irrelative with intensity of stress anisotropy.

Key words: ferromagnetic resonance, muhilayer film, stress anisotropy
