EuMnBi2 i YbMnBi2 are given as experimental examples of topological materials, materials which have electronic bands described by a non-trivial topology, in current research in the field of condensed matter physics. The two compounds are isovalent, which means that they share similar chemical formulas and form the same number of bonds with the surrounding atoms. Despite this property, they crystallize in different crystalline structures and have very different properties. The following work presents theories of resistivity magnetism relevent for these compounds, the specific properties of EuMnBi2 and YbMnBi2 and the influence of the difference in their crystalline structures over their properties. The mechanism of single crystal growth and the process of synthesis will be discussed in detail, as well as the experimental results and the optimization of the method. The compounds were characterized using various experimental techniques whose main working principle will be described. The quality of synthesized crystals will be discussed, as well as how it changed as the method of synthesis was optimized. The results of characterization are presented and compared to the corresponding results from the literature.
