Controlling spin-based phenomena

Topological insulators, nanomagnetic systems, multiferroic materials, or spin structures all possess electronic and magnetic properties that may prove useful in the design of new devices. HZB researchers are analysing these properties and shedding light on spin-based phenomena at high spatial and temporal resolutions. The relevant processes, like domain wall shifts and magnetic excitations, are all taking place in the nanosecond to femtosecond time scale.

Research goal

Analysis of electronic and magnetic properties and interactions within the materials and at interfaces, as well as the identification of parameters to control them.

Competencies

Use of interconnected and complementary experimental stations and methods closely linked with sample growth and characterisation.

Infrastructure

  • BESSY II: ARPES and Spin-ARPES, PEEM, high field XMCD, FEMTOSPEX
