Abstract

Magnetic field-induced strain (MFIS) of 12% is reported in ferromagnetic Ni46Mn24Ga22Co4Cu4 martensite exhibiting non-modulated (NM) tetragonal crystal structure with lattice parameter ratio c/a>1" role="presentation">c/a>1. The strain was measured at ambient temperature in a magnetic field of the order of 1 T. The twinning stress σTW" role="presentation">σTW and the magnetic stress σMAG" role="presentation">σMAG were also measured and the condition for a giant MFIS observation σTWσTW46Mn24Ga22Co4Cu4 martensite by considerable lowering of the σTW" role="presentation">σTW value as compared to the values for NM martensites in ternary Ni-Mn-Ga system.
