Nonlinear and spin-glass susceptibilities of three site-diluted systems
Julio F. Fernández
The nonlinear magnetic and spin-glass susceptibilities in zero applied field are obtained, from tempered Monte Carlo simulations, for three different spin glasses…
Evidence against an Almeida-Thouless line in disordered systems of Ising dipoles
Julio F. Fernandez
By tempered Monte Carlo simulations, an Almeida-Thouless (AT) phase-boundary line in site-diluted Ising spin systems is searched for. Spins interact only through dipolar fields and…
Monte Carlo study of the spin-glass phase of the site-diluted dipolar Ising model
J. J. Alonso, J. F. Fernández
By tempered Monte Carlo simulations, we study site-diluted Ising systems of magnetic dipoles. All dipoles are randomly placed on a fraction x of all L^3 sites of a simple cubic lat…
Equilibrium spin-glass transition of magnetic dipoles with random anisotropy axes on a site diluted lattice
J. F. Fernandez, J. J. Alonso
We study partially occupied lattice systems of classical magnetic dipoles which point along randomly oriented axes. Only dipolar interactions are taken into account. The aim of the…
Continuous spin reorientation in antiferromagnetic films
J. J. Alonso, J. F. Fernandez
We study anisotropic antiferromagnetic one-layer films with dipolar and nearest-neighbor exchange interactions. We obtain a unified phase diagram as a function of effective uniaxia…
Coherence in magnetic quantum tunneling
Julio F. Fernandez
Currently, spin tunneling at very low temperatures is assumed to proceed as an incoherent sequence of events that take place whenever a bias field h(t) that varies randomly with ti…
Ordering of dipolar Ising crystals
J. F. Fernandez, J. J. Alonso
We study Ising systems of spins with dipolar interactions. We find a simple approximate relation for the interaction energy between pairs of parallel lattice columns of spins runni…
Algorithm for normal random numbers
J. F. Fernandez, Carlos Criado
We propose a simple algorithm for generating normally distributed pseudo random numbers. The algorithm simulates N molecules that exchange energy among themselves following a simpl…
