Science Daily  March 9, 2021 Researchers in Japan analyzed the operation of the flux-control (FC) device by measuring the temporal resistance change in the sub-nanosecond region. They showed that the reversal of the FC device becomes faster as the bias current is increased and can be completed by 0.5 ns after the transition of the write current. They reproduced the experimental results by micromagnetic simulations using a head model, confirming that the simulations correctly describe the magnetization dynamics of the actual device. The simulations showed that the recording field gain by the FC device appears with little delay after the rise […]
