Ferromagnetic frozen structures from the dipolar hard spheres fluid at moderate and small volume fractions
Russier, Vincent; Malherbe, Jean G.; Alonso-Pereda, Juan José (IOP Publishing, 2023)
We study the magnetic phase diagram of an ensemble of dipolar hard spheres (DHS) with or without uniaxial anisotropy and frozen in position on a disordered structure by tempered Monte Carlo simulations. The crucial point ... -
Low-temperature spin-glass behaviour in a diluted dipolar Ising system
Alonso-Pereda, Juan José (2015-07-27)
Using Monte Carlo simulations, we study the character of the spin-glass (SG) state of a site-diluted dipolar Ising model. At high dilution, well deep in the SG phase, we find spiky distributions that are strongly ... -
Nature of the spin-glass phase in dense packings of Ising dipoles with random anisotropy axes
Alonso-Pereda, Juan José (2016-09-02)
By Monte Carlo simulations, we study the character of the spinglass (SG) phase in dense disordered packings of magnetic nanoparticles (NPs). We focus on NPs which have large uniaxial anisotropies and can be well represented ... -
Role of positional disorder in fully textured ensembles of Ising-like dipoles
Alonso-Pereda, Juan José; Allés, Bartolome; Russier, Vincent; Malherbe, Jean G. (American Physical Society (APS), 2023-10)
We study by numerical simulation the magnetic order in ensembles of randomly packed magnetic spherical particles which, induced by their uniaxial anisotropy in the strong coupling limit, behave as Ising dipoles. We explore ...
