The technique "µSR" - Muon Spin Rotation, Relaxation or Resonance
A research tool using muons as sensitive local magnetic probes in matter.
Worldwide unique instruments:
The Low-Energy Muon (LEM) beam and µSR Spectrometer for the study of thin films, layers and surfaces;
the high-field instrument (HAL-9500) equipped with specially designed detectors to perform studies in fields up to 9.5 Tesla and at very low temperatures;
and the combination of very-high pressures (up to 2.8 GPa) combined with sub-Kelvin temperatures (GPD).
Lab News & Scientific Highlights
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 ...
