Splet01. maj 2024 · This three-state switching behavior can be controlled by means of magnetic fields and gate voltages, without spin-orbit interactions or magnetic leads, and is a good candidate for spintronic devices such as spin filters or spin memories in future spintronic circuits. Availability of data and materials SpletLatching Hall-effect sensor ICs, often referred to as "latches," are digital output Hall-effect switches that latch output states. Latches are similar to bipolar switches, having a positive B OP and negative B RP, but provide tight control over switching behavior. Latches require both positive and negative magnetic fields to operate. mel weather hourly
