Hysteresis in a Microactuator With Single-Domain Magnetic Thin Films

An actuator with single-domain magnetic thin films is designed to investigate the actuation in the application of a magnetic field. The single-domain magnetic thin film used in this study has high shape anisotropy, and the single-domain magnetization is observed using magnetic force microscope. The hysteresis in the planar deflection of the cantilever beam is found, and the magnetic switching behavior of the single-domain magnetic thin films is also observed in the actuation.
