Abstract

We have found a complete thermoelastic intermartensitic transformation between modulated and unmodulated martensite in single-crystal Ni₅₂Mn_24.5Ga_23.5. This intermartensitic transformation provides a much larger strain than that of the martensitic transformation. A giant switching-like strain of ± 5.0% can be achieved by a small magnetic field of 0.2 T upon the intermartensitic transformation. In the modulated martensite, a large recoverable magnetic-field-induced strain of up to 1.2% has been obtained.
