µSR - Muon Spin Rotation, Relaxation or Resonance: A research tool using muons as sensitive local magnetic probes in matter.
Research at the LMU focuses mainly on magnetic properties of materials and on positive muons or muonium (bound state of a positive muon and an electron) as light protons or hydrogen substitutes in matter.
Worldwide unique: The Low-Energy Muon Beam and µSR Spectrometer for the study of thin films, layers and surfaces, the possibility to perform high-field µSR with a field up to 9.5 Tesla, and the Extraction of Muons On Request for high frequency resolution and slow relaxation measurements.
Call for Proposals

Myonen erhalten Förderung des Schweizerischen Nationalfonds
Das PSI erhält einen NCCR: Mit dem Projekt «Muoniverse» wird die Forschung an den Strahllinien für Elementarteilchen namens Myonen weiter ausgebaut – an der weltweit führenden Anlage für Myonenstrahlen.
Advanced muon-spin spectroscopy with high lateral resolution using Si-pixel detectors
Muon-spin spectroscopy at continuous sources has stagnated at a stopped muon rate of ∼40kHz for the last few decades. The major limiting factor is the requirement of a single muon in the sample during the typical 10µsdata gate window. To overcome this limit ...
Surface-localized magnetic order in RuO2 thin films revealed by low-energy muon probes
Ruthenium dioxide (RuO2) has recently emerged as an altermagnetic candidate, but its intrinsic magnetic ground state in thin films remains widely debated. This study aims to clarify the nature and spatial extent of the magnetic order in RuO2thin films grown under different conditions ...
