Effective Spin-1/2 Description of Transverse-Field-Induced Random Fields in Dipolar Spin Glasses with Strong Single-Ion Anisotropy
S. M. A. Tabei, F. Vernay, M. J. P. Gingras
We present analytical and numerical evidence for the validity of an effective S=1/2 approach to the description of random field generation in S>=1, and especially in an S=1, dipola…
Dy2Ti2O7 Spin Ice: a Test Case for Emergent Clusters in a Frustrated Magnet
Taras Yavors'kii, Tom Fennell, Michel J. P. Gingras +1
Dy2Ti2O7 is a geometrically frustrated magnetic material with a strongly correlated spin ice regime that extends from 1 K down to as low as 60 mK. The diffuse elastic neutron scatt…
Zero-temperature phase of the XY spin glass in two dimensions: Genetic embedded matching heuristic
Martin Weigel, Michel J. P. Gingras
For many real spin-glass materials, the Edwards-Anderson model with continuous-symmetry spins is more realistic than the rather better understood Ising variant. In principle, the n…
Low temperature specific heat and possible gap to magnetic excitations in the Heisenberg pyrochlore antiferromagnet Gd2Sn207
Adrian Del Maestro, Michel J. P. Gingras
The Gd2Sn2O7 pyrochlore Heisenberg antiferromagnet displays a phase transition to a four sublattice Neel ordered state at a temperature near 1 K. Despite the seemingly conventional…
Momentum dependent light scattering in insulating cuprates
F. H. Vernay, M. J. P. Gingras, T. P. Devereaux
We investigate the problem of inelastic x-ray scattering in the spin Heisenberg model on the square lattice. We first derive a momentum dependent scattering operator for th…
