Materials containing triangular structures of magnetic moment are an important pathway to studying unconventional magnetic phenomena that arise from the geometrical frustration....

We propose to solve the long standing controversy regarding the magnetic state of off-stoichiometric Heusler alloys Ni2Mn1.4In0.6 and Ni1.8Co0.2Mn1.4In0.6 at temperatures below...

The system 1T-TaS2 is a charge density wave (CDW) insulator below 180 K that has one residual spin 1/2 for every 13 Ta atoms in the modulated CDW structure. These spins and...

LiFePO4 is cathode material for Li ion batteries. One of the key functional properties is the Li-ion diffusion. Theoretical calculations showed that Li diffusion along the [010]...

Quantum phase transitions (QPT's) are phase transitions that are driven by zero-temperature quantum fluctuations, and are accessed by varying a non-thermal control parameter....

Cs2Cu3SnF12 and Rb2Cu3SnF12 have a distorted kagome structure and the latter exhibits a pinwheel valence bond solid (VBS) state that has been demonstrated by inelastic neutron...

The compounds belonging to the series of TMOs NaM2O4 (M = Ti, V, Mn, Cr) share the same interesting properties: they are all Q1D metallic antiferromagnets with the Na ions...

We plan to measure the electric field distribution in epoxy resin based dielectrics close to breakdown using muons to detect the free charge carriers that may contribute to...

The physics across the phase transitions in solids has been of topical interest in the condensed matter physics. For example, liquid and vapor coexist along the vapor pressure...

The iron-based superconductors are at the forefront of the research on unconventional superconductivity. The Barium-122 systems, doped with electrons, reveal a non-trivial...

This experiment proposes to measure the MuSR signal in undoped phthalocyanine (Pc) samples of NiPc, PbPc, FePc and TiOPc, in order to clarify the existence of the paramagnetic...

ScF3 is a material with the ReO3 structure which shows negative thermal expansion. This experiment will use implanted muons to create an F-mu-F state in this structure and then...

LaCoO3 and A-site Sr doped LaCoO3 have been an intense research area in recent days due to their complex magnetic phase diagram and another additional degree of freedom,...

In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of...

Benzophenone is an ideal material to study vibrations of a muon radical centre with near-IR laser light, as all C=O bonds in solid state are almost parallel to each other and it...

The current experiment proposes to identify and study the spin dynamics of the muon states formed in octabutoxy-phthalocyanine (oBu-H2Pc) using the avoided level crossing...

We have synthesised a novel material IrSr2Sm1.15Ce0.85Cu2O10 . Preliminary magnetic measurements evidence two magnetic transitions at Tc = 125 K and TM2= 6 K. Above Tc however...

It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways....

This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,...

The great majority of known muonium defect centres and muonium substituted organic radicals have essentially spin-only magnetism, with few exhibiting any noticeable departure...
