Magnetic properties of a single transverse Ising ferrimagnetic nanoparticle

Thermodynamic Properties of the Core/Shell Antiferromagnetic Ising Nanocube

“…The compensation point has also been obtained theoretically in Refs. [15,28,35,36] and experimentally by Estrader et al [3] for the magnetization of the core/shell particles based on F e-oxides and Mn-oxides. We can clearly see, at zero temperature, that the M T curves have three saturation magnetizations M sat = −0.218, −0.342, and −0.369 when the core/shell antiferromagnetic interfacial coupling are selected as r cs = −0.1, −0.3, and −0.5, respectively, which indicate that the saturation value of the total longitudinal magnetization decreases with the decrease of r cs .…”

“…They have observed that the system exhibits first-and second-order phase transitions and also critical end points. Recently, Bouhou et al [28] have investigated the effect of the core/shell interfacial coupling, the surface shell exchange coupling, and the surface shell transverse field on the magnetic and thermodynamic properties of an antiferromagnetic core/shell magnetic NP on a HCP lattice. They have found a number of interesting phenomena such as the existence of the compensation temperature.…”
