Ni–Mn–Ga Single Crystal Exhibiting Multiple Magnetic Shape Memory Effects

Both magnetically induced phase transformation and magnetically induced reorientation (MIR) effects were observed in one Ni 50 Mn 28 Ga 22 single crystal sample by direct measurement of the magnetic field-induced strain. We investigated various twinning microstructures ranged from single twin interf...

Zusammenfassung:Both magnetically induced phase transformation and magnetically induced reorientation (MIR) effects were observed in one Ni 50 Mn 28 Ga 22 single crystal sample by direct measurement of the magnetic field-induced strain. We investigated various twinning microstructures ranged from single twin interface to fine twinning and crossing twins to evaluate what controls the apparent twinning stress crucial for MIR. The main challenges for the applications of these effects are outlined.
