Introduction to muon spin rotation and relaxation
Rustem Khasanov
Paul Scherrer Institut, Switzerland
Over the past decades muon spin rotation techniques (muSR) have established
themselves as an invaluable tool to study a variety of static and dynamic phenomena in
bulk solid state physics and chemistry. Common to all these approaches is that the muon
is utilized as a spin microprobe and/or hydrogen-like probe, implanted in the material
under investigation. Recent developments extend the range of application to deeply in
the bulk allowing to perform experiments under the high pressure as well as near the
surface allowing to perform nanometer scale depth resolved experiments on the thin
films and super-lattices. After briefly summarizing the production of so called surface
muons used for bulk studies, and discussing the principle differences between pulsed
and continuous muon beams, the production of keV-energy muon sources will be
discussed. A few topical examples from different active research fields will be
presented to demonstrate the power of these techniques.
