| Abstract Scope |
Magnetic insulators (MIs) offer low magnetic damping, high speed, and fast dynamics that can be beneficial for next-generation spin-electronics applications. A highly promising approach to utilize MIs is to create interfaces between an MI and a non-magnetic material (NM), which can generate new magnetism and enable new ways of controlling MIs with high energy efficiency. This presentation will discuss two of our recent works focusing on creating and controlling novel magnetism at MI/NM interfaces. The first work involves creating ferromagnetism at perovskite interfaces by precisely controlling epitaxial strain. Here, we demonstrate new design rules on how to modify the interfacial charge and spin states that lead to emergent magnetism. The second work presents a novel method for controlling magnetism in van der Waals (vdW) MI/NM interfaces. We demonstrate a deterministic switching of 2D magnets using a spin source vdW material WTe2 via spin-orbit torque. |
