A device and method for high speed metamagnetic resistive switching provides a metamagnetic phase transitioning (MPT) portion formed on a substrate between terminals. The MPT portion is tuned for temperature-responsive transitions between magnetic phases through a transition phase. The phases are delineated by phase boundaries each traversed at different critical temperatures depending on direction of traversal.
