Abstract and Keywords
This article reviews the current status of superconducting spintronics and devices, with particular emphasis on the critical issues and developments needed for their application to low-power quantum computing. It first provides an overview of conventional spintronics before discussing the rationale for superconducting spintronics. It then considers the proximity effects and Josephson junctions in superconductor-ferromagnet heterostructures, along with spin transport in the superconducting state. It also examines the issue of memory in superconducting spintronics, especially with respect to reading and writing magnetic data via superconducting states, and how to generate memory logic in such devices. Finally, it evaluates the potential application of superconductor-ferromagnetic insulator devices as thermoelectric systems in low-temperature electronic circuits.
Keywords: superconducting spintronics, superconducting devices, conventional spintronics, proximity effect, Josephson junctions, superconductor-ferromagnet heterostructures, spin transport, superconducting states, memory logic, superconductor-ferromagnetic insulator devices
