Oscillating Solitons Pinned to a Nonmagnetic Impurity in Layered Antiferromagnets
L. A. S. Mól, A. R. Pereira, W. A. Moura-Melo
We argue that an oscillatory motion of impurity-pinned solitons may occur in layered antiferromagnetic compounds. The characteristic frequencies of these modes, that may be detecte…
Monte Carlo study of the critical temperature for the planar rotator model with nonmagnetic impurities
S. A. Leonel, Pablo Zimmermann Coura, A. R. Pereira +2
We performed Monte Carlo simulations to calculate the Berezinskii-Kosterlitz-Thouless (BKT) temperature for the two-dimensional planar rotator model in the presence of no…
Vortices in the presence of a nonmagnetic atom impurity in 2D XY ferromagnets
L. A. S. Mól, A. R. Pereira, A. S. T. Pires
Using a model of nonmagnetic impurity potential, we have examined the behavior of planar vortex solutions in the classical two-dimensional XY ferromagnets in the presence of a spin…
