# Spin Waves

## Appears In

                        - Nanoscale Magnetic Media Diagnostics by Rippling Spin Waves

Trapped beneath the magnetic tip of a microscale cantilever, spin waves can be used to non-destructively measure the properties of magnetic materials and search for nanoscale defects, especially in multilayer magnetic systems like a typical hard drive, where defects could be buried beneath the surface.
