Ferromagnetic order in dipolar systems with anisotropy: application to magnetic nanoparticle supracrystals
Single domain magnetic nanoparticles (MNP) interacting through dipolar interactions (DDI) in addition to the
 magnetocrystalline energy may present a low temperature ferromagnetic (SFM) or spin glass (SSG) phase according to the underlying structure and the degree of order of the assembly. W...

| description | Single domain magnetic nanoparticles (MNP) interacting through dipolar interactions (DDI) in addition to the
magnetocrystalline energy may present a low temperature ferromagnetic (SFM) or spin glass (SSG) phase according to the underlying structure and the degree of order of the assembly. We study, from Monte Carlo simulations in the framework of the effective one-spin or macrospin models, the case of a monodisperse assembly
of single domain MNP fixed on the sites of a perfect lattice with fcc symmetry and randomly distributed easy
axes. We limit ourselves to the case of a low anisotropy, namely the onset of the disappearance of the dipolar
long-range ferromagnetic (FM) phase obtained in the absence of anisotropy due to the disorder introduced by
the latter.

 V. Russier, who has been one of the Dr. J.-P. Badiali’s PhD students, acknowledges the huge importance
 Dr. J.-P. Badiali had on his carrier. The collaboration which lead to about 15 co-authored publications
 aimed at a theoretical description of the electrochemical double layer which brought together statistical
 physics physicists and electrochemists. It was during this activity that J.P. Badiali urged V. Russier to the
 so-called dipolar hard sphere fluid as a model for molecular solvents. The work presented here dealing
 with another application of this model is in some sense the continuation of this initial training and
 collaboration.
