Emergent electromagnetic induction beyond room temperature

Abstract

Significance Emergent inductors that utilize emergent electric fields generated by the current-induced motion of spiral spin textures have the potential to realize dramatic miniaturization of inductance elements. By using YMn 6 Sn 6 , which has been attracting attention as a kagome lattice magnetic material in recent years, we have realized the room-temperature operation of emergent inductors. This micron-scale emergent inductor device shows not only an inductance as large as a commercially available product but also a sign change of inductance, which is a previously undescribed phenomenon.
