A uSR study of the superconducting ground state in the ternary intermetallics...
The ternary intermetallics, which crystallise in the ThCr2Si2 structure, have been extensively studied mainly because these materials offer a rich variety of exotic ground... -
Examining the topological nature of superconductivity in PdTe2
PdTe2 was found to be superconducting below Tc = 1.7 K and a Type-II Dirac semimetal. A protected bulk Dirac point arises from a band inversion that occurs within the Te... -
Temperature and environment dependence of the isotope effect in muonated radi...
We plan to measure the hyperfine constants for both the muon and the equivalent hydrogen atom in a small muonated radical using time-differential ALC. We will follow this as a... -
Characterizing Mu in 6H-SiC with RF-MuSR
We propose a set of RF measurements on Silicon Carbide (polytype 6H) to identify and characterize the muonium species present below room temperature. One of the main goals of... -
Probing the glass transition in polymers using LF muSR
Nearly all polymers form glasses and the glass transition at temperature Tg dominates many physical properties of polymers that are relevant for their applications. The most... -
The nature of excitations in a molecular Haldane system
It is well known that an S = 1 antiferromagnetic spin chain is predicted to have a quantum disordered ground state and a gap in its excitation spectrum. This so-called Haldane... -

A triangular lattice occupies a special position in the quantum spin-liquid (QSL) physics. Although the triangular-lattice Heisenberg antiferromagnet is known to evade a QSL,... -
Field-induced low-temperature phase in NaO2
Molecular solids like sodium superoxide NaO2 exhibit intricate magnetic behavior despite their simple chemical structure. This is due to the interplay of spin, orbital and... -
Muonium in BeO
BeO is a promising material in order to improve HfO2-based MOSFET devices, and a candidate substitute of HfO2 as high-k gate material. The electrical properties of BeO can be... -
Sample-cooling effects on the field-induced low-temperature magnetic phase in...
Molecular solids like sodium superoxide NaO2 possess relatively simple crystal structures, yet their magnetism is surprisingly complex. This is presumably due to the interplay... -
Quantum magnetism in copper-oxalate networks ranging from isolated triangles ...
The oxalate ligand provides a flexible way of constructing metal organic framework systems based on metallic ions such as Cu and their structures can be finely tuned via careful... -
Spin dynamics and magnetic ordering in the p-orbital molecular solids CsO2 an...
A magnetic response of the alkali-metal superoxides comes from the p-orbital S = 1/2 spins of anionic O2- molecules. As the O2- molecules are highly reorientable and the... -
Field-induced low-temperature magnetic phase in alkali-metal sesquioxides
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... -

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... -
Spin correlations of a triangular-lattice quantum-spin-liquid candidate
A quantum spin liquid (QSL) shows no magnetic order down to zero temperature but the spins are highly entangled. More and more interests are attracted to 2D spin-1/2... -
