It was the purpose of this thesis to evaluate two-dimensional (2D) magneto-thermoelectric (MTE) phenomena in thinner regime. Mostly this work was motivated by the recent discovery of MTE properties in transition metal dichalcogenides (TMD). In general, TMD thin films have attracted much attention due to their very good electrical, optical, and electrochemical properties. However the total amount of studies of the MTE in TMD is rather small compared to the other properties, such as electric, opto-electric, and catalyst. Hence, in this thesis, we aimed to evaluate the MTE properties in TMD materials. Before we started to measure TMDs, we established a measurement platform and studied MTE properties in ferromagnetic CoFeB, and Weyl semimetal Co2MnGa.:1. Introduction
