Spin Ice Thin Film: Surface Ordering, Partial Magnetic Wetting and Emergent Square Ice
L. D. C. Jaubert, T. Lin, T. S. Opel +2
Motivated by recent realizations of DyTiO and HoTiO spin ice thin films, and more generally by the physics of confined gauge fields, we study a…
Color ice states, weathervane modes, and order by disorder in the bilinear-biquadratic pyrochlore Heisenberg antiferromagnet
Yuan Wan, Michel J. P. Gingras
We study the pyrochlore Heisenberg antiferromagnet with additional positive biquadratic interaction in the semiclassical limit. The classical ground state manifold of the model con…
Ab initio determination of spin Hamiltonians with anisotropic exchange interactions: the case of the pyrochlore ferromagnet LuVO
Kira Riedl, Daniel Guterding, Harald O. Jeschke +2
We present a general framework for deriving effective spin Hamiltonians of correlated magnetic systems based on a combination of relativistic ab initio density functional theory ca…
Spin slush in an extended spin ice model
Jeffrey G. Rau, Michel J. P. Gingras
We introduce a new classical spin liquid on the pyrochlore lattice by extending spin ice with further neighbour interactions. We find that this disorder free spin model exhibits a…
