Notes:
We report on strain measurements in Ni-Mn-Ga, Ni-Mn-In, Ni-Mn-Sn and Ni-Mn-Sbpolycrystalline alloys as a function of temperature and magnetic field. Experiments are carried outin the austenitic and martensitic phases of the alloys. It is shown that in the cubic phase themagnetostrain is similar for all systems but by contrast very different behaviour is found when afield is applied in the martensitic phase. In the latter case, magnetic shape memory and magneticsuperelasticity is obtained for Ni-Mn-Ga and Ni-Mn-In, respectively. The physical reasons for thedifferent behaviour are discussed
