Anisotropy of the surface magnetostatic wave spectrum in ferrite films
Surface magnetostatic waves (SMSWs) propagating in thin ferrite films are studied in detail and used widely in spin-wave electronic devices. The dispersion rela tions for waves being excited play an important role in the development and analysis of physical models for cor responding devices. The study is aimed at developing convenient methods for calculating the dispersion rela tions for SMSWs in anisotropic ferromagnetic films. Let us consider films with a cubic magnetic anisotro py ,which are oriented along the planes passing through an axis of the< 110>type.It should be noted in con nection with the problem being considered that the basic material used in spin-wave electronics is yttrium iron garnet (YIG,Y3Fe5O12) belonging to weakly anisotrop ic ferrites with a cubic symmetry of the crystal lattice.Films with crystallographic orientations of the {111} type have found the widest application. At the same time some characteristics of spin-wave devices can be improved by using films with other orientations.In par ticular,it was noted in [1,2] that the thermal stability of the SMSW spectrum for films with the {110} and j 100 (orientations is higher than for {111} films. All these orientations ({ 111 },{110} and {100 }) are particular cases of the model under investigation.
