Pyrochlore magnets of formula R2Ti2O7 or R2Sn2O7 constitute the paradigm for geometrical frustration on a 3D lattice. Spinel compounds CdR2X4, where the R sublattice forms a...

Our recent µSR measurements on a polycrystalline sample of Ru7B3 has shown that this material is an excellent example of broken time reversal symmetry on entering the...

Spins on the kagome lattice are one of the most widely investigated topics in frustrated magnetism. This two-dimensional corner sharing triangular lattice offers a...

We propose to characterize the two magnetic transitions in Nd0.75Gd0.25Rh3B2 and study the spin dynamics and field induced domain rotation via zero field (ZF) and longitudinal...

Among the rare earth titanates and stannates cristallising in the pyrochlore crystal structure, Tb2Ti2O7 is a singular system since its ground state is believed to be a spin...

The The recent discovery of superconductivity in FeAs-containing compounds (often known as the pnictides has provided a great stimulus to experiment and theory in the study of...

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...

LiCuSbO4 is a new 1D S =1/2 frustrated chain compound. Chains with frustrated ferromagnetic J1 and antiferromagnetic J2 interactions are of significant interest due to the rich...

The quaternary boronitride superconductor La3Ni2B2N3-d (Tc~12-14 K) has a layered structure where LaN-LaN-LaN triple layer blocks alternate with NiB layers. These NiB sheets are...

Cs2Cu3SnF12 and Rb2Cu3SnF12 have a distorted kagome structure and the latter exhibits a pinwheel valence bond solid (VBS) state that has been demonstrated by inelastic neutron...

Au4V is an extremely unusual alloy. Neither Au nor V is generally found to carry a magnetic moment in the metallic state, yet the body-centred tetragonal (bct), structurally...

We aim to explore the groundstate of a new near-perfect S=1/2 kagome antiferromagnetic (KAFM) system using MuSR at the lowest possible temperatures. The title compound is...

LiZn2Mo3O8 is a highly unusual geometrically frustrated material: the magnetic moments are associated not with single ions but with small transition-metal clusters. The spin is...

Pure Ho2Ti2O7 exhibits spin ice beahviour. Studies of doped spin ice, replacing Ho with non-magnetic Y, suggest that the spin ice state is present even when the amount of doping...

Recently the coexistence of superconductivity (SC) and antiferromagnetic (AFM) ordering has been reported in CeNi0.8Bi2 with TSC = 4.2 K and TN =5 K, which crystallises in the...

We propose to investigate the effects of the electron- phonon interaction on the time reversal symmetry breaking phenomenon of non-cetrosymmetric superconductors. μSR is...

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...

The recent interest in carbon-based materials like graphene stimulated a deeper analysis of the magnetism in graphite defects. In a previous µSR experiment we observed an...
