The crystal structures and magnetic ordering of layered compounds that have been modified by low temperature chemical methods will be probed using neutrons. The systems...

We propose a MuSR study of the magnetism in Mn-doped ZnGeP2 during this round of experiments using muon spin depolarization measurements in a longitudinal magnetic field. This...

Traditional high-temperature synthesis techniques can be used to vary the composition of K{1-x}Fe{2-y}Se2 up to certain limits. We have found a way to extend the limits on the K...

Open p-shell anionic compounds are model systems where the interplay between charge, lattice, orbital, and spin degrees of freedom leads to complex magnetic behavior. In the...

We propose to continue laser spectroscopy measurements of the muonium (Mu-) centres in n-type doped silicon carbide. Scanning a wide wavelength range, and changing the relative...

1T-TaS2 is a layered material with many intriguing properties that are after four decades still sparking controversial discussions. Due to a charge gap, it has been long...

We propose to study the evolution of ZF-muSR and low-field (100 G) TF-muSR spectra and relaxation times across the charge ordering temperature T0 = 140 K of RbFe2As2 iron based...

We propose a series of measurements to complete the previous direct spectroscopic measurements of the Muonium defect energy levels in Silicon Carbide (SiC; RB110134). We will...

Ce-compounds are well known to present very rich physics and exotic electronic ground state due to the competing RKKY, Kondo and crystal field interactions. Recently CeRuPO...

This is a continuation proposal, for work carried out previously on the EMU and MuSR spectrometers. We have determined that spin fluctuations are present in this system, by...

Spin ice materials exhibit novel magnetic behaviour because of their atomic interactions and geometric constraints of the crystal lattice. This novel behaviour takes the form of...

FeSe1-xSx is an important model system for investigating the relationship between superconductivity and nematicity. The nematicity can be suppressed systematically by the...

Continued investigation of magnetic fluctuations in the Mn-doiped chalcopyrite semiconductor ZnGeP2 is proposed using LF-MuSR depolarization rates. Due to ferromagnetism above...

The layered half-metal Co3Sn2S2 with a Kagomé lattice in the a-b plane has been recently discovered as a magnetic Weyl semimetal, whose Weyl nodes are only 60 meV above the...

The study of organic ferroelectrics based on mixed-stack charge-transfer salts is currently a rapidly developing research field. These materials attract interest as highly...

Single-Molecular Magnets (SMMs) provide access to the mesoscopic world. They possess slow magnetization relaxation due to an energy barrier induced by axial magnetic anisotropy,...

Skyrmions are chiral magnetic spin textures that exist in a variety of different magnetic materials. Skyrmions are usually stabilized in noncentrosymmetric chiral materials by...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent muSR studies of Au NPs encapsulated in mesoporous...

Encouraged by many unconventional magnetic properties in the magnetically frustrated spin-chain compounds of the type A3MM'O6, we have recently synthesized a new member...

We have obtained a LSCOO x = 0.06 single crystal where neutron diffraction shows field induced anti-ferromagnetic order with an onset field in the range 0-1T and increasing...
