dc.description.abstractHyperjemná pole Bhf a magnetické vlastnosti rodiny BaFe2As. Jako důležitý nález, ukazujeme, že není rozumné vztáhnout hyperjemná pole BHF ku průměrnému magnetickému momentu u sloučenin, jak to bylo provedeno v dřívější literatuře.cs
dc.description.abstract-translatedThe hyperfine field Bhf and the magnetic properties of the BaFe2 As2 family are studied using the fully relativistic Dirac formalism for different types of substitution. The study covers electron doped Ba(Fe1−x Cox )2 As2 and Ba(Fe1−x Nix )2 As2 , hole doped (Ba1−x Kx )Fe2As2, and also isovalently doped Ba(Fe1−x Rux )2 As2 and BaFe2 (As1−x Px )2 for a wide range of the concentration x. For the substituted compounds the hyperfine fields show a very strong dependence on the dopant type and its concentration x. Relativistic contributions were found to have a significantly stronger impact for the iron pnictides when compared to bulk Fe. As an important finding, we demonstrate that it is not sensible to relate the hyperfine field Bhf to the average magnetic moment μ of the compound, as it was done in earlier literature.en
