Generalized Spin Glass Relaxation (2009)

Pickup, R M, Cywinski, R, Pappas, C, Farago, B, Fouquet, P

Spin relaxation close to the glass temperature of CuMn and AuFe spin glasses is shown, by neutron spin echo, to follow a generalised exponential function which explicitly introduces hierarchically...

Evidence for time-reversal symmetry breaking in the non-centrosymmetric superconductor LaNiC$_2$ (2009)

Hillier, A. D., Quintanilla, J., Cywinski, R.

The results from muon spin relaxation experiments on the non-centrosymmetric intermetallic superconductor LaNiC$_2$ are reported. We find that the onset of superconductivity coincides with the...

Evidence for time-reversal symmetry breaking in the non-centrosymmetric superconductor LaNiC2 (2009)

Hillier, AD, Quintanilla, J, Cywinski, R

Muon spin relaxation experiments on the noncentrosymmetric intermetallic superconductor LaNiC2 are reported. We find that the onset of superconductivity coincides with the appearance of spontaneous...

High temperature neutron diffraction studies of 0.9BiFeO3-0.1PbTiO3 (2009)

Comyn, TP, Stevenson, T, Al-Jawad, M, Turner, SL, Smith, RI, Bell, AJ, ...

Neutron diffraction data were collected from sintered polycrystalline 0.9BiFeO3-0.1PbTiO3 at temperatures between 293 and 793 K and the crystal and magnetic structures refined by the Rietveld method....

Towards a dedicated high-intensity muon facility (2008)

Cywinski, R, Bungau, A, Poole, M W, Smith, S L, Barlow, R J, ...

We discuss possible designs for a high-intensity, stand-alone muon source dedicated to and fully optimised for μSR studies. In particular, we focus upon the potential implementation of a new...

PAMELA – a model for an FFAG based hadron therapy machine (2007)

Peach, K, Cobb, J, Yokoi, T, Gardner, ISK, Edgecock, R, Poole, MW, ...

Approximately one third of the world’s 15000 accelerators are used for tumour therapy and other medical applications [1]. The characteristics of FFAGs make them ideally suited to such applications,...

Non-fermi-liquid behavior of electron-spin fluctuations in an elemental paramagnet (2002)

Stewart, J.R., Rainford, B.D., Eccleston, R.S., Cywinski, R.

We report for the first time, the observation of non-Fermi-liquid scaling behavior in an elemental paramagnetic metal. Both the dynamical susceptibility and the resistivity of β-Mn are shown to...

DYNAMICAL SUSCEPTIBILITY OF DILUTE (Mo1-xNbx)Fe ALLOYS (1988)

Rainford, B., Moze, O., Mck Paul, D., Lindley, E., Cywinski, R.

Inelastic neutron scattering has been used to measure the linewidth of the dynamical response of Fe impurities in Mo1-xNbx alloys. The character of the local moment, inferred from its relaxation...

LOW-FREQUENCY SUSCEPTIBILITY OF SUPERPARAMAGNETS (1988)

Gray, E., Cywinski, R.

We used a log-normal distribution of activation energies to model the alternating susceptibility of a superparamagnet without interactions. Scaling relationships facilitating the calculation of...

MAGNETIC CORRELATIONS IN Y (Co1-xMnx)2 ALLOYS (1988)

Kilcoyne, S., Hannon, A., Cywinski, R.

SANS has been used to study magnetic correlations in Y (Co1-xMnx)2 alloys with x = 0.05, 0.1 and 0.2. Contrary to previous reports no evidence of ferromagnetism is observed. Instead the correlation...

THE ONSET OF FERROMAGNETISM IN HCP CoCr ALLOYS (1988)

Kilcoyne, S., Hannon, A., Cywinski, R.

Spin correlations close to the critical concentration for ferromagnetism in HCP CoCr have been studied using SANS and a.c. susceptibility. The critical concentration is 69 at.% Co above which the...
