Abstract :
Deformation available to excite ultrasonic vibrations is caused as magnetostriction in a conducting Mn-Zn ferrite crystal when an electric current passes through the crystal. Its conversion efficiency from electrical to mechanical vibrations is very good, because magnetic flux around the current is closed and has no free pole to induce a demagnetization field.
