dc.description.abstract	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.	uk_UA
dc.description.abstract	Однодоменнi магнiтнi наночастинки (МНЧ) iз дипольною мiжчастинковою взаємодiєю можуть окрiм магнiтокристалiчної фази знаходитися у низькотемпературнiй феромагнiтнiй (ФМ) або спiново-склянiй фазах залежно вiд структури та ступеню впорядкування системи. Методом моделювання Монте-Карло в рамках односпiнової чи макроспiнової моделей авторами дослiджується монодисперсна система однодоменних МНЧ, розташованих на вузлах iдеальної ґратки з симетрiєю типу fcc i з довiльно розподiленими осями. Розглядається випадок низької анiзотропiї, зокрема початку зникнення дипольної далекосяжної ФМ фази.	uk_UA
dc.description.sponsorship	We acknowledge important discussions with Dr. J. Richardi, Dr. I. Lisiecki, Dr. T. Ngo, Dr. C. Salzemann, Dr. S. Nakamae, Dr. C. Raepsaet, Dr. J.-J. Weis and Pr. J.J. Alonso. 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. Work performed under grant ANR-CE08-007 from the ANR French Agency. This work was granted an access to the HPC resources of CINES under the allocation 2016-A0020906180 made by GENCI.	uk_UA
