Quantum order by disorder in a semiclassical spin ice
Yang-Zhi Chou, Ying-Jer Kao
We study the S>1 nearest-neighbor Heisenberg model with a ferromagnetic interaction J and a large non-collinear <111> easy-axis anisotropy D on a pyrochlore lattice. For a finite D…

Magnetic correlations in spin ice Ho2-xYxTi2O7 as revealed by neutron polarization analysis
L. J. Chang, Y. Su, Y. -J. Kao +6
We present single-crystal neutron-diffuse-scattering measurements with polarization analysis on the spin ice Ho2-xYxTi2O7 (x = 0, 0.3, and 1). At 2 K, the spin flip scattering patt…

Disorder from disorder and confinement in the quantum Ising model in the pyrochlore lattice
Chyh-Hong Chern, Chen-Nan Liao, Yang-Zhi Chou
At zero temperature, the classical antiferromagnetic Ising model on the pyrochlore lattice is a spin disorder phase of the critical spin correlation. It is a deconfined phase in th…
