Abstract :
Summary form only given. Magnetic shape memory materials are of a great interest for their giant field-induced strain up to 6% and fast response in magnetic field. To date the giant field-induced strain has been observed only in bulk single crystalline material or some specially textured materials. Due to induction of eddy currents the cycling is limited to low frequencies. To increase the frequency range the material can be utilized in the form of a thin layer or ribbon. In analogy with other materials rapid quenching may offer a possibility to prepare a ribbon with a specific texture which may be favorable to MSM effect.
