Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation 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...

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...

We propose to investigate AgFBF4, a compound known for > 20 years, with muon spectroscopy. The scope is to determine the 3D ordering temperature as well as estimate the value...

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...

Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically...

FeSe is a superconductor below 8.5 K. Very recently, we have found superconductivity in a wide compositional range in a series of layered lithium iron selenide hydroxides....

While Y(Mn1-xAlx)2 (x<0.02) is seen as a system of AF coupled local Mn moments (T<110K), alloys with 0.02<x<0.3 show characteristics of a topologically frustrated...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

We propose an investigation of the magnitude and fluctuations of internal magnetic fields in Mn-doped ZnGeP2. This chalcopyrite structured semiconductor has a ferromagnetic (FM)...

Fe3Sn2 is a rare example of an itinerant frustrated ferromagnet (Tc = 640K), with a non-collinear spin structure. It shows a large anomalous Hall resistivity in a low field of...

We aim at performing temperature (2-300K) and magnetic field (0-5T) dependent muon SR on a 1X1 cm2 mosaic, made of 4* 5x5x2 mm3 TbMn0.98Fe0.02O3 single crystals (largest area...

The implanted muon can form a quantum-coherent resonant state when sandwiched between two I=1/2 fluorine ions, where I is the nuclear spin. This state has usually only been for...

We want to isolate the effects of doping, charge localization and local distortion on the transition from insulating antiferromagnet to superconducting metal in YBCO. We choose...

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...

HfNiSn is a semiconducting material with cubic crystal symmetry, and as such it should not show any anisotropy in electronic transport.However, at low temperatures we observe...

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...

We propose a set of RF measurements on Silicon Carbide (polytype 6H) to identify and characterize the muonium species present below room temperature. One of the main goals of...

Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful...

This proposal is part of a long-range program aiming at determining the stable charge-stateconfigurations, site and impurity energy levels (donor and/or acceptor) of hydrogen in...
