Unravelling spin fluctuation components in a stripe-ordered cuprate
In previous experiments at ILL we observed a gap in the magnetic excitation spectrum of the stripe-ordered superconductor (La,Nd)2-xSrxCuO4, x=0.12. We observed a spin gap of... -
Magnetic Excitation Spectrum of the Frustrated Antiferromagnet SrYb2O4
In SrYb2O4 the magnetic Yb3+ ions form sub-lattices of double chains running parallel to the crystallographic c-axis with frustrated first and second neighbour antiferromagnetic... -
Quantum-Critical Dynamics of a 3-dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of... -
Rattling modes in new thermoelectrics
NaxCoO2 has an exceptional combination of thermoelectric properties, including low thermal conductivity, and it is currently under consideration for use in power recovery and as...
