One-way shape memory effect due to stress-assisted magnetic field-induced phase transformation in Ni2MnGa magnetic shape memory alloys Academic Article uri icon


  • One-way shape memory effect is achieved utilizing stress-assisted field-induced martensitic phase transformation in Ni2MnGa magnetic shape memory alloy single crystals. Depending on temperature, one-way and reversible magnetic field-induced strains of up to 3.1% and 0.3% are attained under stresses as high as 110 MPa and 24 MPa, respectively. These bias stress levels are more than one order of magnitude higher than the previously reported values obtained from field-induced martensite reorientation. 2006 Acta Materialia Inc.
