Ni-Mn-Ga magnetic shape memory alloy was studied at different conditions during austenite-martensite and martensite-austenite transformations. Simultateous change of magnetization and strainh has been observed. Thermomechanical and magnetic history of the sample seems to have only very weak influence on the character of austenite-martensite transformation

Slitiny s tvarovou pamětí Ni-Mn-Ga byly studovány za různých podmínek během transformací austenit-martensit a martensit-austenit. Současně byly sledovány změny magnetizace a deformace. Termomechanická a magnetická historie vzorku mají pouze slabý vliv na charakter transformace austenit-martensit
