Abstract
The magneto-shape memory behavior of a Co-32 wt.% Ni single crystal is investigated by vibrating sample magnetometry and magnetodilatometry measurements. It is found that the single crystal with [001] orientation exhibits a high-saturation magnetization of 133 Am ²/kg and a high Zeeman energy in martensitic state. The maximum of 4.2% reversible strain was induced by applying 12 kOe magnetic field at room temperature. Both magnetization and magnetic field-induced-strain saturated at an applied magnetic field of 12 kOe.
