Laboratory for Muon Spin Spectroscopy (LMU)

Kagome_Lattice_NatComm2023_PSI

The PSI Laboratory for Muon Spin Spectroscopy uses the fundamental particles from the Swiss Muon Source SµS to investigate matter and materials. 

Call for Proposals

Next Deadline: Call II/2025 June 01, 2025.

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).

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 ...
