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...

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...

Skyrmions are chiral magnetic spin textures that exist in a variety of different magnetic materials. Skyrmions are usually stabilized in noncentrosymmetric chiral materials by...

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...

We measure electron-hole recombination rate in low-temperature pure silicon using the photo-MuSR technique. The previous works have measured the recombination rate down to -30...

The polar magnetic semiconductors GaV4S8 and GaV4Se8 have recently attracted attention as one of only two families of bulk materials hosting Néel-type skyrmions: nano-sized...

In the 5d layered perovskite material, Sr2IrO4, spin orbit coupling and strong electron correlations combine to give rise to a spin-orbit coupled Mott insulator, with a...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

From our current results of (Nd1-xCax)2Ir2O7, the internal field at 1.5 K increases with increasing the hole doping, the relaxation rate at 50 K increases with increasing the...

Using the Emu spectrometer at ISIS we have recently studied charge carrier transport in the technologically important molecule 8-hydroxy-quinoline aluminium, by probing the...

Gaining control of the building blocks of magnetic materials will enable the design and growth of bespoke magnetic devices. However, the ability to tune the magnetic...

Using nitronyl nitroxide radicals it is possible to prepare purely organic ferromagnets without inclusion of any transition metal or lanthanide ions. Muons are uniquely...

Skyrmions are topologically protected, nano-sized objects existing in the spin textures of a range of magnetic materials. Using LF muSR we see an enhanced relaxation and strong...

Understanding the normal phase behaviour of the iron based superconductors is very important in order to shed new light on the physics of these complex materials. Mn impurities...

These half-Heusler compounds are also semi-metals, with low carrier densities and non-trivial topological features. The crystal structures are also non-centrosymmetric, which is...

The new molecular magnet bis(2,3-dimethylpyridinium) tetrabromocuprate (DIMPY) is a strong-leg spin ladder with a quantum critical point at 3 T separating a low-field...

One goal of our research into the nanoengineering of molecular magnets is a detailed understanding of the relationship between the structure and composition of a system and its...

We propose longitudinal field muSR on a 2D molecular magnetic system which has been suggested to have an unusual B-T phase diagram. Our goal is to probe the transition from...

Pyrochlore magnets are one of the cornerstones of frustrated magnetism, with two interpenetrating lattices of corner-sharing tetrahedra on which magnetic ions can be placed. By...

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...
