Intrinsic and extrinsic tunability of Rashba spin-orbit coupled emergent inductors
Jun’ichi Ieda, Yuta Yamane
Abstract
By integrating the spin-orbit coupling, both the amplification mechanism of the quantum version of inductance, and the origin of ``negative inductance'' that was not possible in a single device, are clarified. The findings will stimulate research in miniaturization of power supply circuits and electromagnetic noise reduction based on negative inductance, which will ultimately determine the size and weight of electronic devices. The achievement here will help open up a new technological field of ``power spintronics'', in which power is controlled via spin-based quantum technology.
