Magnetic hysteresis behavior of granular manganite LaCaMnO nanotubes
M. I. Dolz, S. D. Calderón Rivero, H. Pastoriza +1
A silicon micromechanical torsional oscillator is used to measure the hysteresis loops of two manganite La_0.67Ca_0.33MnO_3 nanotubes at different temperatures, applying an externa…
Micromagnetic simulation study of a disordered model for one-dimensional granular perovskite manganite oxide nanostructures
P. Longone, F. Roma
Chemical techniques are an efficient method to synthesize one-dimensional perovskite manganite oxide nanostructures with a granular morphology, that is, formed by arrays of monodom…
Nonequilibrium dynamics of the three-dimensional Edwards-Anderson spin-glass model with Gaussian couplings: Strong heterogeneities and the backbone picture
F. Roma, S. Bustingorry, P. M. Gleiser
We numerically study the three-dimensional Edwards-Anderson model with Gaussian couplings, focusing on the heterogeneities arising in its nonequilibrium dynamics. Results are analy…
Unconventional critical activated scaling of two-dimensional quantum spin-glasses
D. A. Matoz-Fernandez, F. Roma
We study the critical behavior of two-dimensional short-range quantum spin glasses by numerical simulations. Using a parallel tempering algorithm, we calculate the Binder cumulant…
Critical behavior and out-of-equilibrium dynamics of a two-dimensional Ising model with dynamic couplings
Oscar A. Pinto, Federico Romá, Sebastian Bustingorry
We study the critical behavior and the out-of-equilibrium dynamics of a two-dimensional Ising model with non-static interactions. In our model, bonds are dynamically changing accor…
Numerical integration of the stochastic Landau-Lifshitz-Gilbert equation in generic time-discretisation schemes
Federico Romá, Leticia F. Cugliandolo, Gustavo S. Lozano
We introduce a numerical method to integrate the stochastic Landau-Lifshitz-Gilbert equation in spherical coordinates for generic discretization schemes. This method conserves the…
