A group of materials that experience excitations which can be described by the Dirac equation are referred to as the Dirac matter. Graphene, topological insulators, 3D Dirac semimetals, Weyl semimetals, and many others belong to this group. Here, we study the properties of these three compounds; EuCd2As2, EuCd2Pb2, and EuCd2P2. According to the previously published measurements, these are considered to be Dirac materials. All three compounds are isostructural and mutually similar by many different properties. The most interesting, in the context of the Dirac matter, are their magnetic properties, originating from the arrangement of europium atoms. In this work, we explain the synthesis of single crystals of the three compounds in detail. We present the results of testing the structure of the synthesized single crystals by performing the X-ray diffraction method on powder samples. Using the Laue diffraction method, we find the orientations of the crystal axes for the synthesized single crystals, and using the X-ray fluorescence spectroscopy we determine their elemental compositions. Furthermore, utilizing the obtained information on the orientation, we measure the transport properties of single crystals of the three materials along the a priori determined crystal axes. We use a low-temperature measurement setup to test how the electrical resistance depends on the temperature, magnetic field and we find the corresponding Hall coefficients.
