The structure of intercalated water in superconducting NaCoO1.37DO: Implications for the superconducting phase diagram
D. N. Argyriou, C. J. Milne, N. Aliouane +7
We have used electron and neutron powder diffraction to elucidate the structural properties of superconducting \NaD. Our measurements show that our superconducting sample exhbits a…
Isotope effect in quasi-two-dimensional metal-organic antiferromagnets
P. A. Goddard, J. Singleton, C. Maitland +9
Although the isotope effect in superconducting materials is well-documented, changes in the magnetic properties of antiferromagnets due to isotopic substitution are seldom discusse…
Role of anisotropy in the spin-dimer compound BaCuSi2O6
Suchitra E. Sebastian, P. Tanedo, P. A. Goddard +9
We present results of magnetisation and electron paramagnetic resonance experiments on the spin-dimer system BaCuSi2O6. Evidence indicates that the origin of anisotropic terms in t…
Les Houches 2011: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, B. Gripaios, F. Moortgat +141
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our report includes new agreem…
A new collective phenomenon arising from spin anisotropic perturbations to a Heisenberg square lattice manifested in paramagnetic resonance experiments
S. Cox, R. D. McDonald, J. Singleton +6
We report unexpected behaviour in a family of Cu spin- 1/2 systems, in which an apparent gap in the low energy magneto-optical absorption spectrum opens at low temperature. This pr…
Very weak electron-phonon coupling and strong strain coupling in manganites
S. Cox, J. C. Loudon, A. J. Williams +4
The coupling of the manganite stripe phase to the lattice and to strain has been investigated via transmission electron microscopy studies of polycrystalline and thin film manganit…
