摘要：
The focusing and caustic effects of magnetoelastic waves (MEW) in Galfenol crystals (Fe100-xGax) in the vicinity of magnetoelastic resonance are considered. It is shown that the caustic pattern of magnetoelastic waves differs significantly from the phonon caustic pattern, and the directions of MEW caustics are controlled by the magnitude of the external magnetic field. The region of magnetic field in which the MEW caustics can be observed is determined.
