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…
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…
Angle-dependent magnetoresistance oscillations due to magnetic breakdown orbits
A. F. Bangura, P. A. Goddard, J. Singleton +6
We present experimental evidence for a hitherto unconfirmed type of angle-dependent magnetoresistance oscillation caused by magnetic breakdown. The effect was observed in the organ…
Persistence to high temperatures of interlayer coherence in an organic superconductor
John Singleton, PA Goddard, A Ardavan +5
The interlayer magnetoresistance of the organic metal \cuscn is studied in fields of up to 45 T and at temperatures from 0.5 K to 30 K. The peak in seen in in…
A photonic bandgap resonator to facilitate GHz frequency conductivity experiments in pulsed magnetic fields
R. D. McDonald, J. Singleton, P. A. Goddard +2
We describe instrumentation designed to perform millimeter-wave conductivity measurements in pulsed high magnetic fields at low temperatures. The main component of this system is a…
