Mixed-bond spin-1 Ising model with nonlinear interactions for the Fe-Mn alloys
A. S. Freitas, Douglas F. de Albuquerque, I. P. Fittipaldi +1
In this letter, we apply the mixed-bond spin-1 Ising model to the study of the magnetic properties of Fe-Mn alloys in the phase by employing the effective field theory (EFT). H…
Representation for the Pyrochlore Lattice
André Luis Passos, Douglas F. de Albuquerque, João Batista Santos Filho
This work aims to present a representation for the Kagomé and pyrochlore lattices for Monte Carlo simulation and some results of the critical properties. These geometric frustrated…
Study of the first-order phase transition in the classical and quantum random field Heisenberg model on a simple cubic lattice
Ricardo de Sousa, Douglas F. de Albuquerque, Alberto S. Arruda
The phase diagram of the Heisenberg ferromagnetic model in the presence of a magnetic random field (we have used bimodal distribution) of spin S=1/2 (quantum case) and …
Phase Diagram of mixed bond Ising systems by use of Monte Carlo and the effective-field theory
J. B. Santos-Filho, N. O. Moreno, Douglas F. de Albuquerque
The phase transition of a random mixed-bond Ising ferromagnet on a cubic lattice model is studied both numerically and analytically. In this work, we use the Cluster algorithms of…
Magnetic Properties of the Metamagnet Ising Model in a three-dimensional Lattice in a Random and Uniform Field
J. B. dos Santos-Filho, Douglas F. de Albuquerque
By employing the Monte Carlo technique we study the behavior of Metamagnet Ising Model in a random field. The phase diagram is obtained by using the algorithm of Glaubr in a cubic…
Heisenberg model in a random field: phase diagram and tricritical behavior
Douglas F. de Albuquerque, A. S. de Arruda
By using the differential operator technique and the effective field theory scheme we study the tricritical behavior of Heisenberg classical model of spin-1/2 in a random field. Th…
