Аннотация
2D surface magnetostatic waves (SMSWs) have been investigation in dynamic magnonic crystals (DMCs) produced by a surface acoustic wave (SAW) in a structure with an yttrium−iron garnet (YIG) film; the technique and results of this investigation are presented. The methods used to study the dependences as functions of the angle between the SMSW and SAW wave vectors are described. The angular dependences of the magnonic bandgap frequencies have been measured. It has been established that bandgaps with the transformation of a reflected SMSW into other types of magnetostatic waves (MSWs) exist at any value of the angle, while bandgaps in which a reflected SMSW does not experience transformation appear in a certain narrower range of angles. The angles of the directions of the wave vectors and the Poynting vector of the reflected SMSW have also been measured. These results are in good agreement with the calculation performed using the isofrequency curves method and the laws of inelastic SMSW scattering from a SAW.
