The Fermi surface is the surface in reciprocal space that separates occupied from unoccupied electron states. Its shape is derived from the periodicity and symmetry of the crystalline lattice and from the occupation of electronic energy bands. Various experimental techniques are used to determine the Fermi surface in a given material. Angle-resolved photoemission spectroscopy (ARPES) is the most direct and the leading experimental probe for obtaining the band structure of a material. Another viable option is exploiting the quantum oscillation phenomena. When the magnetic field is applied to a system of free-charged fermions, their energy states quantize into Landau levels. In a quantum oscillation experiment, the external magnetic field is varied, which causes Landau levels to pass over the Fermi level. This in turn results in oscillations of the electronic density of states at the Fermi level, and with it, oscillations in various properties, such as resistivity and magnetic susceptibility. The oscillation frequency is proportional to the extremal area of Fermi surface elements in a plane perpendicular to the applied magnetic field. Using different angles of external field, one can reconstruct elements of the Fermi surface contributing to oscillations. Dirac materials are a class of materials where the low-energy excitation spectrum can be effectively described by the Dirac equation. They share a property of forming the symmetryprotected Dirac nodes (or lines) on valence and conductive band crossings, with bands linear in close vicinity of nodes. These symmetries are different for different materials, but their net effect is to preserve Dirac nodes. Seemingly diverse materials such as high-temperature dwave superconductors, superfluid phases of 3He, graphene, and topological insulators possess properties that are a direct consequence of the Dirac spectrum of the quasiparticles and are universal. Universal properties include the response to impurities and magnetic fields, suppressed backscattering, transport properties, and optical conductivity. Dirac materials we focused our research on are topological insulators Bi1.1Sb0.9TeSe2 and Bi1.1Sb0.9Te2S, nodal-line semimetals Zr1−xHfxSiS and quasi-1D TaNiTe5 with topologicaly protected states.
