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).

Evidence of antiferromagnetism in ultrathin metallic (111)-oriented LaNiO3 films
Antiferromagnets with exotic spin textures promise low-power spintronic devices with extremely high operating frequencies and resistance to external perturbations. In particular, the combination of highly tunable correlated electron physics, as in complex oxides, with metallicity and antiferromagnetism is desirable but exceedingly rare. LaNiO3, the lone example of a perovskite nickelate which is metallic across all temperatures, has long been a promising candidate, but the antiferromagnetic metallic state has remained elusive. We demonstrate the emergence ...
Origin of the Suppression of Magnetic Order in MnSi under Hydrostatic Pressure
We experimentally study the evolution of the magnetic moment 𝑚 and exchange interaction 𝐽 as a function of hydrostatic pressure in the zero-field helimagnetic phase of the strongly correlated electron system MnSi. The suppression of magnetic order at ≈1.5 GPa is shown to arise from the 𝐽 collapse and not from a quantum fluctuations induced reduction of 𝑚. Our work provides benchmarks ...
