Partial freezing of a Kagome Magnet
Ever since the first published consideration of the ground state of a triangular lattice of Ising spins by PW Andersen in the 50's, the pursuit of materials with geometrically... -
Frustration-stabilized skyrmions in centrosymmetric compounds
Skyrmions are chiral magnetic spin textures that exist in a variety of different magnetic materials. Skyrmions are usually stabilized in noncentrosymmetric chiral materials by... -
Determination of the Magnetic Properties of LaFeAs1-xPxO Across Multiple Magn...
LaFeAs1-xPxO has recently been proposed to display unusual properties as a function of P doping with two distinct superconducting (SC) domes separated by a possible AFM phase as... -
Quasi two-dimensional molecular layers separated by magnetic and non-magnetic...
Recent progress in the field of molecular magnetism has shown the clear potential for gaining control over the structural building blocks of molecular materials in order to... -
Impurity-induced frustration in La2CuO4
We plan to investigate by means of zero-field muSR the doping dependence of the sublatticemagnetization in La2Cu1-xZnxO4 and in La2Cu1-xMgxO4. In both systems Cu2+ S=1/2 spins... -
Hydrogen impurity in solar cell materials CIGS and CZTS
In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive... -
Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -

A µSR stoichiometry study of TixV1-x alloys superconductivity in the presen...
This is a continuation proposal, for work carried out previously on the EMU and MuSR spectrometers. We have determined that spin fluctuations are present in this system, by... -

Metastable skyrmion lattice phase in Cu2OSeO3
Skyrmions are topologically protected, nano-sized objects which have been shown to exist in the spin textures of a range of magnetic materials. As we have recently demonstrated,... -
Direct measurement of magnetoelectric coupling - a new room temperature multi...
We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field... -
Determining the ground state in the metallic ferroelectric LiOsO3
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... -
Field-induced Tomonaga-Luttinger Liquid phase in a spin ladder
The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3.0(3) T separating a low-field... -
Dilution-induced spin glass in Na2IrO3: a MuSR study
We plan to investigate Na2IrO3 samples with a partial substitution of Na by means of a transition metal element (the cases of TM = Co, Ni, Cu and Zn will be considered). The... -
MuSR study to investigate a small moment magnetic ordering in Ce(Os1-xIrx)2Al...
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... -
Fluctuating stripes in an insulating hole-doped antiferromagnet
In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped... -
Frustration-stabilized skyrmions in centrosymmetric compounds
Skyrmions are chiral magnetic spin textures that exist in a variety of different magnetic materials. Skyrmions are usually stabilized in noncentrosymmetric chiral materials by... -
Interaction of muonium centres and excess carriers in highly injected silicon
We have developed a method to measure carrier recombination lifetime in crystalline silicon with the photo-muSR technique. The key of the method is to measure the dependence of... -
The nature of excitations in a molecular Haldane system
It is well known that an S = 1 antiferromagnetic spin chain is predicted to have a quantum disordered ground state and a gap in its excitation spectrum. This so-called Haldane...
