Paper Abstract

Present publication gives a detailed report about the experimental results obtained concerning the effect of external constant stress on the magnetic field controlled strain response during the cyclic change of the magnetic field. Simultaneously we represent a brief overview of the most important structural and magneto-mechanical properties of Ni48Mn30Ga22 - family magnetic shape memory alloys. We also discuss the physical mechanism of this effect using our last model developments.
