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
Structural characterisation of emerging functional materials: when you need muons and neutrons from across Europe to build a full picture
Researchers from Durham University and colleagues from Rutgers (The State University of New Jersey) and the University of Edinburgh have collaborated with teams from ISIS, the Institut Laue-Langevin (ILL) and the PSI Center for Neutron and Muon Sciences to carry out a full characterisation of the double perovskite Pb2MgReO6.
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.
Quantenmaterial unter Druck
Hoher Druck verstärkt die Supraleitung in einem Quantenmaterial und verändert seine Eigenschaften. Forschende des PSI haben den mikroskopischen Mechanismus hinter diesem Effekt aufgedeckt.
