This proposal is part of our project to investigate the unusual physics of 5d transition metal oxides. In particular, we are studying two samples of the chemical composition...

The discovery of superconductivity in ThCr2Si2 type tetragonal Fe-based compounds (i.e. YFe2Ge2) have generated considerable interest. Recently we found bulk superconductivity...

Strong spin-orbit coupling (SOC) has often lead to exotic properties in otherwise banal pool of 'paramagnetic' heavy ion oxides. In this context d4 Ir systems are exciting...

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...

Zn-doped barlowite, ZnxCu4-x(OH)6FBr, is a new experimental realisation of an S = 1/2 kagome antiferromagnet in which the ground state may be tuned from a Néel ordered state to...

Quantum spin liquid (QSL) states emerge when the arrangement of magnetic moments in a material frustrates magnetic interactions and low spin magnetic moments allow for strong...

A series of cyanide-bridged molecular magnets incorporating chiral ligands will be invstigated using muon spin relaxation. The magnets combine Ni(II) with M(III) (M=Fe,Cr,Co)....

The magnetic properties of a Terbium single ion magnetic system will be studied using implanted muons. The system is based on a polyoxometallate ion that provides good isolation...

We aim at exploring the ground state of new Cu2+ S=1/2 kagome compounds, isomorphic to the now-celebrated Herbertsmithite, namely CdCu3(OH)6Cl2 and MgCu3(OH)6Cl2. Due to the...

The noncentrosymmetric half-Heusler semimetals RTBi (R=rare earth, T=Pt, Pd) have recently been proposed, according to electronic structure calculations, as plausible 3D...

Our muSR study on Ce(Os1-xFex)2Al10 with x=0.4, which reveals long range magnetic ordering below 24K from the heat capacity, shows unexpected behaviour. The muSR spectra only...

In order to explore quantum spin ice physics, we wish to focus on the non-Kramers Pr-based pyrochlores with general formula Pr2M2O7 (M =Sn, Zr, Hf). There is a recent...

The Mn6 single molecule magnet shows to date the highest anisotropy barrier for a transition metal cluster. Low lying excited states in the energy level diagram of the molecule...

Recently, a new family of ternary platinum phosphide superconductors have been synthesised with the chemical formula APt3P (A = Sr, Ca, and La, with Tc’s of 8.4, 6.6, and 1.5 K,...

Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly...

A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+)....

The frustration of triangular antiferromagnets with isotropic interactions leads to a variety of ground states even for classical spins. In regions where several classical...

LiOsO3 is a very unusual metallic ferroelectric. This experiment aims to distinguish between two contrasting possibilities for the ground state of this material which can be...

The combination of strong magnetic frustration and low spin found in the S=1/2 quantum antiferromagnet is believed to lead to non-classical magnetic behaviour, and in particular...

The proposal requests time on OSIRIS to measure the low-energy magnetic fluctuations in CeRhSi3. This compound is a noncentrosymmetric superconductor under pressures of ~10...
