A model for vortex formation in magnetic nanodots
S. A. Leonel, I. A. Marques, P. Z. Coura +1
We use Monte Carlo simulation to study the vortex nucleation on magnetic nanodots at low temperature. In our simulations, we have considered a simple microscopic two-dimensional an…

Phase diagram of the antiferromagnetic XY model in two dimensions in a magnetic field
A. S. T. Pires, B. V. Costa, R. A. Dias
The phase diagram of the quasi-two-dimensional easy-plane antiferromagnetic model, with a magnetic field applied in the easy plane, is studied using the self-consistent harmonic ap…

Diagram for vortex formation in quasi-two-dimensional magnetic dots
J. C. S. Rocha, P. Z. Coura, S. A. Leonel +2
The existence of nonlinear objects of the vortex type in two-dimensional magnetic systems presents itself as one of the most promising candidates for the construction of nanodevice…
