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
Next Deadline: December 01, 2026.

ISIS-PSI Muon Collaboration Meeting
On July 21, 11 members of the ISIS Muon Group and 12 of the PSI Laboratory for Muon Spin Spectroscopy met at PSI for a collaboration meeting.
Quantum material under pressure
High pressure enhances superconductivity in a quantum material and alters its properties. PSI researchers have uncovered the microscopic mechanism behind this effect.
Thermodynamic Evidence for Pressure-Driven Evolution towards Weak-Coupling Superconductivity in Pb
The thermodynamic critical field Bc provides direct access to the superconducting condensation energy, yet its pressure dependence has been studied much less extensively than that of the transition temperature. Here, muon-spin-rotation relaxation measurements ...
