Abstract

As novel tools to study magnetic shape memory alloys, a high-speed optical microscope system and a measurement system of magnetocaloric effects (MCEs) in pulsed magnetic fields are developed. Using the high-speed imaging system, successive changes in the surface morphology are visualized in the process of magnetic field-induced reverse martensitic transformation in Ni ₄₅Co₅Mn_36.7In_13.3. The MCEs of Gd studied in pulsed fields show reasonable agreement with the earlier results obtained in steady fields. Application of high magnetic fields up to 55 T realizes a gigantic adiabatic heating of 63 K.
