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…
A microscopic model for spiral ordering along (110) on the MnSi lattice
John M. Hopkinson, Hae-Young Kee
We study an extended Heisenberg model on the MnSi lattice. In the cubic B20 crystal structure of MnSi, Mn atoms form lattices of of corner-shared equilateral triangles. We find an…
