Vortices, skyrmions, and chirality waves in frustrated Mott insulators with a quenched periodic array of impurities
arXiv:1607.07100 · doi:10.1103/PhysRevB.94.174420
Abstract
Finite- magnetic instabilities are rather common in frustrated magnets. When the magnetic susceptibility is maximized at multiple- vectors related through lattice symmetry operations, exotic magnetic orderings such as vortex and skyrmion crystals may follow. Here we show that a periodic array of nonmagnetic impurities, which can be realized through charge density wave ordering, leads to a rich phase diagram featuring a plethora of chiral magnetic phases, especially when there is a simple relation between the reciprocal vectors of the impurity superlattice and the magnetic -vectors. We also investigate the effect of changing the impurity concentration or disturbing the impurity array with small quenched randomness. Alternative realizations of impurity superlattices are briefly discussed.
