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…

Exchange parameters of copper-based quasi-two-dimensional Heisenberg magnets measured using high magnetic fields and muon-spin rotation
P. A. Goddard, J. Singleton, P. Sengupta +9
Pulsed-field magnetization experiments (fields of up to 85 T and temperatures down to 0.4 K) are reported on nine organic Cu-based two-dimensional (2D) Heisenberg magnets.…

Magnetic order in the quasi-one-dimensional spin 1/2 chain, copper pyrazine dinitrate
T. Lancaster, S. J. Blundell, M. L. Brooks +5
We present the first evidence of magnetic order in the quasi-one-dimensional spin 1/2 molecular chain compound, copper pyrazine dinitrate Cu(C4H4N2)(NO3)2}. Zero field muon-spin re…
