Magnetic Shape Memory Phenomena
Result description
Giant magnetically induced strain (MFIS) up to 50 times to the strain of giant magnetostriction was observed in some Heusler alloys particularly in Ni-Mn-Ga. In analogy with the shape memory phenomenon this effect was called Magnetic shape memory (MSM) effect. The effect includes two different phenomena; mag-netically induced martensite (MIM) transformation and magnetically induced reorientation (MIR) occurring in martensite phase. Transformation behavior, structure of the martensite and phenomenology of the magnetically induced reorientation is described. The phenomenology of MIR is based on Heusler Ni-Mn-Ga compounds. The simple model is presented and its prediction tested. Different forms of the materials and its suitability for MIR effect are discussed.
