"Magnetoacoustics and acoustoelectronics," session of the scientific council on acoustics of the Russian Academy of Sciences

A topical session of the Scientific Council on Acoustics of the Russian Academy of Sciences, 'Magnetoacoustics and Acoustoelectronics' was held at Syktyvkar State University'. Effect of ultrasound on the structural transition and the shape memory effect in a ferromagnet presented the results of research into the acoustic properties of NiMnFeGa polycrystals. The nonthermal mechanism of the ultrasonic effect on the structural transition was proved using a pulsed technique. It was found that the contributions of precession and longitudinal oscillations of magnetization intensity to the dynamic properties always coexist and are additive.
