A perspective on curvilinear magnetism

Abstract

By exploring geometry-governed magnetic interactions, curvilinear magnetism offers a number of intriguing effects in curved magnetic wires and curved magnetic films. Recent advances in experimental techniques change the status of curvilinear magnetism, allowing the exploitation of 3D curved nanomagnets in emerging devices with numerous applications. Here, we provide our Perspective on the recent progress, challenges, and prospects of curvilinear magnetism with a special focus on novel physical effects caused by tailoring curvature and topology of conventional magnetic materials.
