# Dynamic spin-charge coupling: spin Hall magnetoresistance in non-magnetic conductors

## TL;DR

This paper explores how spin and charge currents interact dynamically in non-magnetic conductors, enabling electrical detection of electron spin resonance through impedance measurements influenced by spin relaxation and diffusion.

## Contribution

It demonstrates that spin dynamics can be directly observed via electrical impedance, revealing a new method to study spin phenomena in non-magnetic materials.

## Key findings

- Electrical impedance reflects spin dynamics
- Electron spin resonance can be detected electrically
- Spin relaxation and diffusion define key frequency scales

## Abstract

The dynamic coupling between spin and charge currents in non-magnetic conductors is considered. As a consequence of this coupling, the spin dynamics is directly reflected in the electrical impedance of the sample, with a relevant frequency scale defined by spin relaxation and spin diffusion. This allows the observation of the electron spin resonance by purely electrical measurements.
