In the present paper, the thermodynamics of three-dimensional impurity magnetopolaron under strong parabolic potential is investigated. To this aim, we first analytically solved the Schrodinger equation to have the complete energy spectrum in the presence of spin–orbit interaction. We equally use the canonical ensemble approach to obtain the partition function before calculating the thermodynamic parameters. Afterward, we found a great dependence of those thermodynamic parameters such as entropy and heat capacity on spin–orbit interaction (SOI). From this investigation, we found that there are some particular values of SOI for which we have a minimum values reached by the entropy as well as in the presence of magnetic field than temperature. This study allows us to conclude that SOI is a very useful parameter in order to build stable quantum system.
