Název v původním jazyce
Hyperfine fields in the BaFe2As2 family and their relation to the magnetic moment
Popis výsledku v původním jazyce
The 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(Fe1MINUS SIGN x Cox )2 As2 and Ba(Fe1MINUS SIGN x Nix )2 As2 , hole doped (Ba1MINUS SIGN x Kx )Fe2As2, and also isovalently doped Ba(Fe1MINUS SIGN x Rux )2 As2 and BaFe2 (As1MINUS SIGN 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 ? of the compound, as it was done in earlier literature.
