Frustration-stabilised high-field skyrmions
Magnetic skyrmions are nanometric topological vortex-like spin textures that appear in select materials and have lately attracted a lot of attention due to their numerous... -
Iron-based superconductors with molecular spacer layers: probing Li diffusion...
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... -
Spin dynamics of the Heisenberg triangular antiferromagnet KCrO2
The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been... -
Spin-orbit transitions in CoV3O8
Strong orbital mixing resulting from local distortions in the crystal field can mix higher energy orbital states with the ground state. We propose to characterise this mixing in... -
Spin Dynamics in the isotopically enriched spin ice 162Dy2Ti2O7
In an attempt to study the dynamics of Dy2Ti2O7 measured using muons we have made a sample of 162Dy2Ti2O7 where the 161 and 164 isotopes are reduced to a minimum (max. 0.6% of... -
Muon probes of hydrogen-bond network in supercooled water
Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and... -
Investigating Magnetic Ordering in Ba2MnWO6 and Sr2MnWO6
Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically... -
Magnetism and superconductivity in hyperexpanded fullerides close to the Mott...
The fcc polymorph of the hyperexpanded fulleride Cs3C60 can be driven to a bulk suprconducting state without symmetry change by the application of pressure. Its Tc passes... -
μSR investigations of multiferroic system RCrTiO5 (R= rare-earth)
We are currently investigating multiferroic system RCrTiO5 (R= rare-earth) using bulk measurements and have found interesting magnetic properties. To understand the nature of... -
Ultrafast motion of molecular rotors in metal-organic frameworks: a muon-spin...
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... -
Isotope dependence of the Néel Temperature in cuprates
The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent... -
Muon Spin Relaxation and ALC Resonance in Magnetic and non-Magnetic Oxalate S...
Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a... -
Studies of Muon-Beam-Induced currents in semi-imsulating GaAs
This proposal is a continuation of our recent proposal RB 610004 where this partcurrent measurements) was not completed due to the reduced beam intensity. Currents experiment... -
Studying the metamagnetism of FeCl2 and FeBr2 using HiFi
Work on the iron halides FeX2 has led to the models of A-type antiferromagnetism and the tricritical point in magnetic systems. Here we wish to carry out decoupling experiments... -

Soft chemistry tuning between magnetism and superconductivity in K{1-x}Fe{2-y...
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... -
Low Temperature Study of the Cluster Glass Phase in Ni(TCNQ)2
Recently there has been an M(TCNQ)2, where M=Mn, Co, Fe and Ni, series synthesised where all samples formed a stochiometric glassy ferromagnetic salt. We have focused on the... -
Muonium in widegap oxides
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... -
μSR study on Heisenberg spin ½ dimer NH4CuPO4·H2O
Heisenberg spin 1/2 systems show exotic nature of ground state, which gives rise to a number of interesting quantum phenomena, like being a state of quantum mechanically... -
muSR study of a relaxor ferromagnet
As a consequence of cation disorder, the compound La3Ni2SbO9 behaves as a new type of magnetic material, a "relaxor ferromagnet", somewhat analogous to a relaxor ferroelectric,...
