Electronic structure and magnetism of a ferromagnetic insulator Cs2AgF4: explanation for a lilac colour and a prediction for the anisotropic g factor
R. J. Radwanski Z. Ropka
Magnetic properties of stechiometric Cs2AgF4 have been calculated within a very strong correlation limit taking into account a low-symmetry crystal field and the intra-atomic spin-…
Crystal-field states in NaCoO2 and in wet cobalt superconductors (NaxCoO2)
R. J. Radwanski Z. Ropka
We claim that for calculations of the electronic structure of 3d oxides very strong electron correlations have to be taken into account similarly to those assumed in many-electron…
Crystal field and spin-fluctuations in heavy fermion metal CeAl3, YbRh2Si2 and UPd2Al3*
R. J. Radwanski Z. Ropka
We have shown the existence of localized crystal-field states in conducting magnetic materials coexisting with conduction electrons in CeAl3, UPd2Al3 and YbRh2Si2. We point out tha…
Crystal field states in conducting magnetic materials: NdAl2, UPd2Al3 and YbRh2Si2
R. J. Radwanski Z. Ropka
The existence of CEF states and the magnetism in conducting compounds NdAl2, UPd2Al3 and YbRh2Si2 is discussed. We point out that in metallic compounds localized crystal-field stat…
Electronic structure and magnetism of LaVO3 and LaMnO3
R. J. Radwanski Z. Ropka
In this contribution we derive and discuss energy levels of the strongly-correlated d2 configuration of the V3+ ion (LaVO3) and of d4 configuration of the Mn3+ ion (LaMnO3) in the…
