Charting the increase in spin fluctuations as we approach the critical point ...
The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,... -
The coupling of spin and charge correlations in La2-xSrxCuO4
Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed... -

Recently, our neutron scattering experiments on electron doped BaFe2-xNixAs2 and hole doped Ba1-xKxFe2As2 suggest that the presence of both high-energy spin excitations giving... -
Does the muon reach thermal equilibrium in a frustrated magnet?
The usual assumption that the muon's polarisation relaxes to zero at long times may be incorrect at high B and low T: for 5T and 30mK the Brillouin function gives P=49%. We plan... -
Magnetic order of Jeff =1/2 moments in the antifluorite (NH4)2IrCl6 Mott insu...
Magnetic materials containing Ir4+ ions can give rise novel Jeff=1/2 magnetic moments due to the strong spin-orbit coupling. Their magnetic interactions depend on the exchange... -
