摘要：
Reflection and refraction of an acoustic beam at the boundary between a liquid and a magnetoacoustic material is considered in the region of the orientational phase transition of the material in magnetic field. For the boundary between water and hematite, the possibility of controlling the angles of refraction and the wave transformation amplitudes is numerically demonstrated. The longitudinal displacement and the splitting of an acoustic beam at the boundary between the aforementioned media are investigated as functions of the external magnetic field.
