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
SμS call for proposals II-26 is open
The call for SμS proposals II-26 (deadline 01 June 2026) is open now.
Experimental observation of short-range magnetic correlations in amorphous Nb2O5 and Ta2O5 thin films
We use muon spin rotation/relaxation/resonance (μSR) to investigate the magnetic properties of niobium pentoxide (Nb2O5) and tantalum pentoxide (Ta2O5) thin films. In both oxides, we observe a magnetic response at the lowest available temperature of 2.8 K ...
