Dynamics of Spin Textures

Cover
From: FWI Annual Report 2011
Illustration: Katrin Kerbusch

Nanoscale spin textures are the building blocks for present magnetic data storage devices, in particular hard disk drives. However, future memory and logic applications need to match the demand for an increasing data density, read/write performance, and energy efficiency. For the technological development, it is crucial to gain knowledge on the physics governing the magnetization dynamics of nanoscale spin textures. We investigate such dynamics by direct imaging with x-ray microscopy; a technique that achieves a combined resolution of approximately 10 nanometers and 10 picoseconds in space and time, respectively.

 

Research Topics

  • Dynamics of ferromagnetic spin textures
  • Spinvortices in ferromagnetic multilayers
