摘要
Fast magnetization switching with minimum heat generation is explored based upon magnetization dynamics and optimal stochastic control method. For current spin current based magnetic device, pulse shape optimization provides significant Joule heating reduction. For future spintronic device without charge moving, the minimum amount of heat generated during magnetization switching is fundamentally constrained by magnetization switching speed and magnetization nonvolatility.
