Magnetic Susceptibility of Cylindrical Quantum Dot with Aharonov-Bohm Flux: Simultaneous Effects of Pressure, Temperature, and Magnetic Field

Abstract

Using canonical ensemble, we have studied the magnetic properties of a cylindrical GaAs quantum dot in this paper. The system is under the direct influence of external static electric and magnetic fields and an Aharonov-Bohm magnetic flux. Considering the temperature- and pressure-dependent effective parameters, the magnetic susceptibility is calculated and plotted in different regimes. Results clearly show the magnetic susceptibility, magnetic transition, and critical points strongly depend on temperature, pressure, and magnetic field. Moreover, Aharonov-Bohm magnetic flux has considerable effects on the magnetic susceptibility of the system.
