Binary mixtures of magnetic shape-anisotropic particles: the role of depletant — Margaret Rosenberg1, •Ekaterina Novak2, Elena Pyanzina2, and Sofia Kantorovich1 — 1University of Vienna, Vienna, Austria — 2Ekaterinburg, Russia
The introduction of non-magnetic particles into a dispersion of magnetic soft (or hard) spheres is recognized to promote the phase separation of the system. Our goal is to explore whether a comparable effect exists in binary mixtures of magnetic shape-anisotropic particles. In this paper, specifically, we undertake a theoretical and computational study of systems comprising either ellipsoids or platelets. We scrutinize the microstructure to assess if the introduction of depletants leads to quantitative or qualitative changes in the radial distribution functions, structure factors, orientational correlations, bond order parameters and static magnetic susceptibility. This research has been partially supported by the RSF Grant No. 19-72-10033. Computer simulations were performed at the Vienna Scientific Cluster (VSC-4).
Keywords: dipolar magnetic platelets and ellipsoids; binary mixtures; theoretical and computational investigation
