µSR Study to Investigate the Magnetism of Ca3Cu1-xMn1+xO6 (x = 0.07)
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... -
Low temperature magnetic order and spin dynamics in Ho2Ir2O7
Ho2Ir2O7 has a cubic pyrochlore structure. Trigonal crystal fields at both the Ho and Ir sites create Ising-like moments that can order in a non-collinear arrangement with... -
Muon Spin Relaxation study on Quantum Spin Liquid candidates Tm3Sb3M2O14 (M =...
Quantum spin liquid (QSL) state is a state that spins are highly entangled and frustrated even at absolute zero temperature, which has attracted lots of attentions due to its... -
Search for monopoles in spin ice via the exterior field distribution
Bramwell et al. have provided an elegant demonstration of dynamics in magnetic monopoles in spin ice measured by muons implanted inside the sample. However, it is likely that... -
Ion dynamics in Potassium Ordered & Disordered KxCoO2
We have recently presented a novel method to study ion-dynamics in solids using muSR via the hopping rate (nu). We have previously and successfully applied this method to study... -
RF decoupling of the F-mu-F state
NMR has become an extremely sophisticated experimental technique because of the use of pulse sequences which allow the control and manipulation of a nuclear spin system or... -

A hidden spin liquid state in strongly correlated FeCrAs
In this continuation proposal we will conclude our muon study of FeCrAs, a recently re-examined material that displays many of the above characteristics, suggesting that it is a... -
Coupling of chains in a new, highly tuneable, isostructural series of model q...
Here we propose measurements on a unique, newly synthesized series of coordination polymers based on chains of Cu2+ ions. These have been designed with the intention of... -
Tuning the low-temperature magnetism of spin ice Dy2Ti2O7: Y-substitution and...
The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose... -
The search and optimisation of Delta0 resonances in TIPS-Pentacene in solution
To the best of our knowledge, there is no previous work on using muons to measure photo-excited states in organic semiconductors or related materials. Our photo-excitation ideas... -
MuSR studies of Alpha-Mn2-xCrxO3(x=0 and 10 %)
MuSR is useful technique/probe in studying small magnetic moment and also identifying magnetic order (short-range or long-range) in a magnetic material.Earlier report on neutron... -
Short range magnetic order in the compositionally modulated Bi2Cr4/3Ni2/3O6 p...
It is particularly challenging to synthesize a novel multiferroic material as it seems that the mechanisms that allow ferromagnets and ferroelectrics to work are mutually... -
Discovery of slow magnetic fluctuations in the nematic phase of FeSe1-xSx
In most unconventional superconductors, the importance of antiferromagnetic fluctuations is widely acknowledged. In addition, cuprate and iron-pnictide superconductors often... -
Detailed investigation of the magnetic interaction as a function of temperature
In the series R2PdSi3,the Nd compound is considered to be an anomalous as it orders ferromagnetically (TC= 16 K) with a weak frequency-dependent ac susceptibility (χ)... -
Magnetic structure of magnetocaloric manganites
Magnetic cooling has recently become the focus of cooling system technology as it boasts important advantages in terms of power consumption and for the environment e.g. not... -
Investigation of the magnetic phases of the charge transfer compound CuTCNQ
The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It...
