Abstract

Spin resonance goes ballistic Electron spin resonance produced by high-frequency magnetic or electric fields has applications in fields as diverse as medicine and quantum information. A new variant of the phenomenon is reported in this issue: ballistic spin resonance. This form does not require external driving fields. Instead, it is produced when electrons bouncing back and forth in micrometre-scale channels of a two-dimensional semiconductor structure undergo spin resonance through an effective magnetic field that arises due to their spin-orbit interaction. The effective field oscillates due to repeated reflections at the channel walls, with typical frequencies (in the ∼20–100 GHz range) that are attractive for modern spin resonance applications.
