Abstract
The launching and propagation of pure shear surface waves (SSW) in magnetostrictive polycrystalline ferrite were studied. The results show that SSW have lower sensitivity to surface quality than Rayleigh waves, but the launching effectiveness by a meander-type transducer is lower than for Rayleigh waves. The variation in phase velocity of SSW on a magnetic field was 4.5%, which can be of interest in applications.
