The magnetocaloric effect, thermo-magnetic and transport properties of LiH diatomic molecule

Abstract

This research article investigates the effects of magnetic and Aharanov-Bohm (AB) fields on the thermo-magnetic and transport properties and magneto-caloric effect (MCE) of Lithium Hydride (LiH) modelled by the Varshni potential. So, the Schrödinger equation in 2D is solved under the influence of external fields and Varshni potential using the functional analysis approach (FAA) to obtain the energy equation and wave function, respectively. The accessible energy levels are summed to obtain the partition function, which is used to obtain the aforementioned properties. The influences of the magnetic and AB fields on the above-mentioned properties have been examined over a broad temperature region. The susceptibility has only positive values in different scenarios analysed, which implies paramagnetism. The temperature dependence of the magnetic entropy (magneto-caloric effect) changes shows a decreasing tendency. This research could find applications in molecular physics and inspire discussions and studies on MCE for several diatomic molecules.
