Antiferromagnetic Ising model on the sorrel net: a new frustrated corner-shared triangle lattice

John M. Hopkinson, Jarrett J. Beck

We study the antiferromagnetic classical Ising (AFI) model on the sorrel net, a 1/9th site depleted and 1/7th bond depleted triangular lattice. Our classical Monte Carlo simulation…

Dimensional crossover of a frustrated distorted kagome Heisenberg Model: Application to FeCrAs

Travis E. Redpath, John M. Hopkinson, Alton A. Leibel +1

Motivated by recent experimental work on FeCrAs, we study the magnetic properties of classical spin models on the hexagonal FeP/ZrNiAl structure (space group ). W…

Spin ice on the trillium lattice studied by Monte Carlo calculations

Travis E. Redpath, John M. Hopkinson

We study a local ferromagnetic Ising model for classical spins on the trillium lattice. The ground state of this model features two spins out(/in) and one spin in(/out) on each tri…

Origin and consequence of an unpinned helical magnet: application to partial order in MnSi under pressure

John M. Hopkinson, Hae-Young Kee

We study a classical ferromagnetic Heisenberg model in the presence of Dzyaloshinskii-Moriya interactions on the corner-shared triangle lattice formed by the Mn sites of MnSi. We s…

Fate of partial order on the trillium and distorted windmill lattices

Sergei V. Isakov, John M. Hopkinson, Hae-Young Kee

The classical Heisenberg model on the trillium and distorted windmill lattices exhibits a degenerate ground state within large- theory, where the degenerate wavevectors form a s…

Classical antiferromagnet on a hyperkagome lattice

John M. Hopkinson, Sergei V. Isakov, Hae-Young Kee +1

Motivated by recent experiments on Na_4Ir_3O_8 [Y. Okamoto, M. Nohara, H. Aruga-Katori, and H. Takagi, arXiv:0705.2821 (unpublished)], we study the classical antiferromagnet on a f…
