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... -
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... -

Multiple phase transitions in U2Pt2Sn studied with muon-spin-rotation and rel...
U2Pt2Sn crystallizes in the tetragonal Zr3Al2-type structure (P42/mnm, Z = 4), where uranium atoms occupy two different sites. Our measurements of bulk properties have shown... -
Muon-spin rotation study of the in-plane magnetic penetration depth of REFe_(...
We propose a TF-muSR investigation of the superconducting properties of the REFe_(1-y)Ru_yAsO_{1-x}F_x compound (RE=La, Sm). In this system the substitution of Fe by the... -
Magnetism in RT2Zn20: below and beyond the Stoner limit
Spontaneous ferromagnetism occurs when exceeding the "Stoner limit", a condition requiring the potential (Coulomb) energy to exceed the kinetic energy cost of splitting the... -
A MuSR study of the superconductivity in ACa2Fe4As4F2 (A = K, Rb, Cs)
The iron pnictide (Fe-Pn) superconductors were the second family of high temperature superconductors to be discovered and have a number of different crystal structures. We... -
Muon spin relaxation studies of KTCNQ and related compounds
Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns... -
Chemical control of structures and properties of layered oxide chalcogenides
The crystal structures and magnetic ordering of layered compounds that have been modified by low temperature chemical methods will be probed using neutrons. The systems... -
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... -
Probing superconductivity, static magnetism and light ion diffusion in molecu...
In 2012 we demonstrated that molecular spacer layers could be intercalated in between FeSe layers resulting in a dramatic enhancement of the critical temperature: FeSe is itself... -
Li+ Diffusion Behaviour of Activated Carbon-treated Li4Ti5O12
We propose to carry out muon-spin relaxation to examine Li+ diffusion in AC-treated Li4Ti5O12 which contains a small amount of rutile TiO2. Measurements will be carried out over... -
Superconductivity and the FμF state in ACa2Fe4As4F2
Materials with a layered structure have been the subject of great interest as potential candidates for high-temperature superconductors. The ACa2Fe4As4F2 family of materials... -
Pressure effect on high-temperature multiferroic CuO studied by a single crys...
We propose to perform neutron diffraction experiment under high pressure condition, using a single crystal of CuO on WISH beamline. This monoxide is known as a multiferroic... -
Field-induced low-temperature magnetic phase in alkali-metal sesquioxides
Open p-shell anionic compounds are model systems where the interplay between charge, lattice, orbital, and spin degrees of freedom leads to complex magnetic behavior. In the... -
Dynamics of the quasi-two dimensional XXZ honeycomb antiferromagnet BaNi2V2O8
We propose to perform zero-field muon spin rotation studies of S=1 honeycomb antiferromagnet BaNi2V2O8 which is an ideal physical realization of the quasi-2D magnetic system.... -
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... -
The Frustrated Magnetic Order of Ba3BIr2O9, B = Y or Sc.
Studies of iridium-based compounds are at the forefront of solid state physics research. In these materials the electronic configurations are driven by strong spin-orbit... -
