The visualized diffraction pattern of the surface spin wave beam excited by the linear transducer in tangentially magnetized ferrite film was compared with calculated in-plane distribution of magnetic potential of this beam. It is found that distribution of the wave magnetic potential and experimental diffraction pattern (distribution) of the spin wave in the film plane are in good agreement not only for the film area, where is localized main diffractive beam, but also for the area where the maxima of lower order are located.

Good Agreement

Visualized diffraction patterns describing in-plane distribution of the backward spin wave beam, excited by linear transducer, are investigated for the case when the spin wave length is much smaller than the transducer length. The angular width of the spin-wave beams is founded for several geometries experimentally and theoretically. There is good agreement between the experimental and theoretical values of the angular beam width.

Visualized diffraction patterns describing in-plane distribution of the surface spin wave beam, excited by linear transducer, are investigated for the case when the spin wave length is much smaller than the transducer length. On the basis of experimental diffraction patterns and on the basis of theoretical calculations (both numerically and based on obtained previously general formula) the angular width of the spin-wave beams is founded for several geometries. There is good agreement between the experimental and theoretical values of the angular beam width.

The Relationship

Microwave magnetic induction structure of a surface spin wave propagated in a free ferrite film is calculated. It is found that vector lines of magnetic induction represent vortexes localized near both surface of the ferrite film. The relationship between microwave magnetic induction structure and microwave electric field structure of spin wave are demonstrated.
