Abstract
The purpose of this paper is to study the thermodynamic equilibrium properties of acollection of non-interacting three-dimensional (3D) magnetically anisotropic nanoparticlesin the light of classical statistical physics. Pertaining to the angular dependence (α) of the magnetic field with the anisotropy axis, energy landscape plots are obtained whichreveal a continuous transition from a double well to a single well for and show an asymmetric bistable shape for other values ofα. The present analysis is related to the interpretation of equilibrium magnetization andstatic susceptibility of a nanomagnetic system as a function of external magnetic field,B, andtemperature, T. The magnetization and susceptibility confirm the non-Langevin behaviour ofmagneto-anisotropic monodomain particles. The susceptibility analysis establishesthe ferromagnetic-, antiferromagnetic- and paramagnetic-like coupling for variousα. This study reveals the essential role of magneto-anisotropic energy in the interpretation ofthe magnetic behaviour of a collection of non-interacting single-domain nanoparticles.
