Ising superconductivity: A first-principles perspective

Abstract

The recent discovery of Ising superconductivity has garnered much interest due in part to the resilience of these superconductors to large in-plane magnetic fields. In this Perspective, we explain the basic concepts that define the behavior of Ising superconductors, provide an overview of the electronic structure and magnetic properties with a focus on NbSe2, summarize key experimental observations that have been made in this class of superconductors, highlight the role that defects and proximity-induced effects at interfaces have on Ising superconductivity, and finally discuss the prospects for observing Ising superconductivity in bulk materials.
