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
The stripe state at 1/8 Ba doping hosts optimal superconductivity in La-214 cuprates under low in-plane stress
The cuprate system La2−xBaxCuO4 (LBCO) exhibits a pronounced sensitivity to in-plane uniaxial stress, particularly near the 1/8 doping anomaly, where stripe order strongly suppresses bulk superconductivity. ...
Unified Pressure and Field Response Across Distinct Charge-Order Regimes in Ti-Doped CsV3Sb5
The cuprate system La2−xBaxCuO4 (LBCO) exhibits a pronounced sensitivity to in-plane uniaxial stress, particularly near the 1/8 doping anomaly, where stripe order strongly suppresses bulk superconductivity. ...
Competing Ordering Modes in the Distorted Quantum Kagome Material Clinoatacamite Cu2Cl(OH)3
We have studied the magnetic properties of clinoatacamite Cu2Cl(OH)3, the parent compound of the quantum spin liquid candidate herbertsmithite and a long-standing puzzle among frustrated quantum magnets ...
