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…
Magnetic friction due to vortex fluctuation
R. A. Dias, M. Rapini, P. Z. Coura +1
We use Monte Carlo and molecular dynamics simulation to study a magnetic tip-sample interaction. Our interest is to understand the mechanism of heat dissipation when the forces inv…
Monte Carlo Simulations of Ultrathin Magnetic Dots
M. Rapini, R. A. Dias, D. P. Landau +1
In this work we study the thermodynamic properties of ultrathin ferromagnetic dots using Monte Carlo simulations. We investigate the vortex density as a function of the temperature…
Phase transition in ultrathin magnetic films with long range interactions
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: A orde…
