Magnetic domain-twin boundary interactions in Ni-Mn-Ga

Veligatla, M.; García-Cervera, C.J.; Müllner, P. (2020-04)

The stress required for the propagation of twin boundaries in a sample with fine twins increases monotonically with ongoing deformation. In contrast, for samples with a single twin boundary, the stress exhibits a plateau ...
Sensitivity of twin boundary movement to sample orientation and magnetic field direction in Ni-Mn-Ga

Veligatla, M.; Titsch, C.; Drossel, W.-G.; García-Cervera, C.J.; Müllner, P. (2019)

When applying a magnetic field parallel or perpendicular to the long edge of a parallelepiped Ni- Mn-Ga stick, twin boundaries move instantaneously or gradullay through the sample. We evaluate the sample shape dependence ...
