Material Parameters for Faster Ballistic Switching of an In-Plane Magnetized Nanomagnet

High-speed magnetization switching of a nanomagnet is necessary for faster information processing. The ballistic by pulsed magnetic filed promising candidate the high-speed switching. It known that speed can be increased increasing magnitude field. However it difficult to generate strong and short field pulse in small device. Here we explore another direction achieve designing material parameters such as anisotropy constant, saturation magnetization, Gilbert damping constant. We perform macrospin simulations in-plane magnetized nano magnets with varying parameters. results are analyzed based on dynamics energy density contour. show width required reduced constant or decreasing magnetization. also there exists an optimal value minimizes
