dc.description.abstract [eng] We study temperature, magnetic field and strain amplitude dependences of the Young's modulus and ultrasonic absorption in the cubic phase of stoichiometric Ni2MnGa single crystal, using longitudinal oscillations (90 kHz) along [100] direction. We show that the additional softening of the Young's modulus below the Curie temperature, usually considered as elastic premartensitic phenomenon, originates instead from conventional microeddy current relaxation associated with individual domain wall motion. In general, existing controversial experimentally observed damping and "elastic" softening behaviours are controlled by a combination of micro- and macroeddy current relaxations, operating at different spatial scales and over distinct frequency ranges.
