摘要：
We study magnetic shape memory alloy Ni(46)Mn(24)Ga2(2)Co(4)Cu(4) showing up to 12% magnetic field-induced strain (MFIS). The MFIS is mediated by motion of the compound twin boundaries (CTBs) in non-modulated tetragonal crystal lattice. We present temperature dependences of the twinning stress sigma (TW)(T), tetragonality ratio, and magnetic anisotropy energy density K-u(T), used for magnetic stress sigma(mAG)(T) calculations. With temperature increasing, the twinning stress for CTBs decreases with the slope of -0.02 MPa/K, twice slower than observed for type I twin boundaries in 10M Ni-Mn-Ga martensite. We found and explained existence of temperature window, within which the giant MFIS is observed. (C) 2016 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
