dc.description.abstractŠtudovali sme tetragonálnu fázu CuMnAs ktorý je kľúčový materiál pre antiforromagnetickú spintroniku. Hlavným výsledkom je porovnanie elektrónovej štruktúry vypočítanej za pomoci LSDA+U s optickou a fotoemissnou spektroskopiousk
dc.description.abstract-translatedThe tetragonal phase of CuMnAs progressively appears as one of the key materials for antiferromagnetic spintronics due to efficient current-induced spin-torques whose existence can be directly inferred from crystal symmetry. Theoretical understanding of spintronic phenomena in this material, however, relies on the detailed knowledge of electronic structure (band structure and corresponding wave functions) which has so far been tested only to a limited extent. We show that AC permittivity (obtained from ellipsometry) and UV photoelectron spectra agree with density functional calculations. Together with the x-ray diffraction and precession electron diffraction tomography, our analysis confirms recent theoretical claim [Phys. Rev. B 96, 094406 (2017)] that copper atoms occupy lattice positions in the basal plane of the tetragonal unit cell.en
