Non-centrosymmetric superconductors (NCS) are believed to be good candidates for unconventional superconductivity. In particular, there is the possibility of Cooper pairs with...

Motivated by work showing that magnetic coupling between TCNQ anions in potassium TCNQ (KTCNQ) can be changed simply by changing the aromatic substituents, we seek to qunatify...

The ternary intermetallics, which crystallise in the ThCr2Si2 structure, have been extensively studied mainly because these materials offer a rich variety of exotic ground...

All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make...

We propose to carry out a muSR study of the spin dynamics in two single crystal samples of Yb2Ti2O7. Both samples are notionally stoichiometric but they have been prepared using...

This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen...

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...

This proposal is part of a long-range program aiming at determining the stable charge-stateconfigurations, site and impurity energy levels (donor and/or acceptor) of hydrogen in...

Low-dimensional systems exhibit some of the most interesting physical phenomena seen in condensed matter physics. One-dimensional (1D) spin chain is important for understanding...

Green dioptase is a naturally occurring mineral, that has a deep green colour, similar to that of an emerald, and with a chemical formula of CuSiO3.H2O. The Cu lies in quasi-1D...

Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous...

In this proposal we plan to investigate the anomalous magnetism of Ce in recently discovered CeO0.5F0.5BiS2 and Sr0.5Ce0.5FBiS2 magneto-superconductors. The proposed compounds...

In recent years, amphidynamic crystals have gained more and more attention as a state of matter somehow intermediate between solids and liquids. In fact, although these systems...

We are currently investigating Haldane spin-chain compounds [PRB 2017] of the type R2BaNiO5 (R = rare earth) using bulk measurements and have found the multifunctional...

A new layered iridate material, Cu2IrO3, has been fabricated. This material is isostructural with the much-studied Na2IrO3 and has a nearly ideal honeycomb structure that should...

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...

In the present project we will focus on critical behaviour of Cu3(pyrazine)[W(CN)8]2 revealing magnetic phase transition at Tc=43 K. The findings will be compared to those...

Tb2Ti2O7 is a pyrochlore antiferromagnet that has previously been viewed as a spin liquid. This description fails to describe key features of its physics and more recently the...

We propose to characterize the basic muonium/hydrogen configurations in selected rare-earth sesquioxides with the basic crystallographic structures: neodymium oxide (hexagonal A...

We intend to detail the muonium dynamics and investigate the interaction with charge carriers in n-type ZnSe. A doped ZnSe sample (resistivity=10^4 Ohm.cm, n=10^13 cm^-3) is...
