| contents | Monte Carlo study of the anisotropic three-dimensional heisenberg model in a crystal field R. T. S. Freire B. V. da Costa J. A. Plascak Física, Astronomía y Matemáticas We study the phase diagram of the three-dimensional classical ferromagnetic Heisenberg model with an easyplanecrystalline anisotropy and an easy-axis exchange anisotropy through Monte Carlo simulations. We employthe Metropolis algorithm together with single-histogram techniques in order to characterize the transitionsin each region of the phase diagram. Our results reveal, besides the disordered phase, the existence of Ising-likeand XY-like ordered phases which are separated by a first-order transition line. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434221 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2A Vol.34 |
