Hysteretic structural changes within five-layered modulated 10M martensites of Ni-Mn-Ga(-Fe)
Original language description
Ni-Mn-Ga-based Heusler alloys are broadly studied for their magnetic shape memory (MSM) functionality originating from coupling between ferroelastic and ferromagnetic orders. The ferroelastic order is established after martensitic transformation. Formed ferroelastic domains with different orientation are separated by twin boundaries. In modulated phases, these boundaries are extremely mobile and can be manipulated by magnetic field. Thanks to these, the single crystals of five-layered modulated 10M martensite of Ni-Mn-Ga exhibits magnetically induced reorientation (MIR) of ferroelastic (twin) domains in a moderate field of the order of 0.1 T [1, 2]. This results in 6 % magnetic field induced strain (MFIS) down to liquid helium temperature [3]. Such unique behaviour makes the 10M martensite a perfect candidate for applications in actuators, sensors and energy harvesters.
