Effect of magnetostatic interactions on twin boundary motion in Ni-Mn-Ga magnetic shape memory alloy
Original language description
We investigated the effect of magnetostatic interactions on the field-induced reorientation of martensite variants in Ni 50.0 Mn 27.5 Ga 22.5 . The reorientation, achieved by sweeping a single Type-II twin boundary along the sample, was triggered by a twinning stress of about 0.1 MPa. However, depending on the initial position of the twin boundary, the magnetic field providing the critical stress varied in the range 8?32 kA/m. By taking into account the variants sizes and their mutual interactions, we explained the observed dependence of the switching field on the location of the boundary. The resulting match between model predictions and measurements illustrates the fundamental role played by demagnetization effects and magnetostatic interactions in magnetic shape memory effect.
