Spin Dynamics Simulation of the magnetization reversal process in FM/AFM bilayer structures by Anisotropic Heisenberg Model
E. B. Santos, P. Z. Coura, R. A. Dias +2
We have studied the magnetization reversal process in FM/AFM bilayer structures through of spin dynamics simulation. It has been observed that the magnetization behavior is differe…
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…
Phase transition in ultrathin magnetic films with long-range interactions: Monte Carlo simulation of the anisotropic Heisenberg model
M. Rapini, R. A. Dias, B. V. Costa
Ultrathin magnetic films can be modeled as an anisotropic Heisenberg model with long-range dipolar interactions. It is believed that the phase diagram presents three phases: An ord…
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…
Velocity, temperature and normal force dependence on friction: An analytical and molecular dynamic study
R. A. Dias, P. Z. Coura, M. Rapini +1
In this work we propose an extension to the analytical one-dimensional model proposed by E. Gnecco (Phys. Rev. Lett. 84:1172) to describe friction. Our model includes normal forces…
Temperature Dependent Molecular Dynamic Simulation of Friction
R. A. Dias, M. Rapini, P. Z. Coura +1
In this work we present a molecular dynamics simulation of a FFM experiment. The tip-sample interaction is studied by varying the normal force in the tip and the temperature of the…
