Violation of the Curie law in Na2V3O7 as the crystal-field and spin-orbit coupling effect
R. J. Radwanski, Z. Ropka
We have shown that the observed drastic violation of the Curie-Weiss law in Na2V3O7, reported in Phys. Rev. Lett. 90 (2003) 167202, is caused by conventional crystal-field interact…

Comment on Phys. Stat. Sol. (b) 236 (2003) 281 paper by A. M. Oles "Orbital ordering and orbital fluctuations in transition metal oxides"
R. J. Radwanski, Z. Ropka
We argue that the 3A2 state considered by Oles in Phys. Stat. Sol. (b) 236 (2003) 281 for the d2 system occurring in the V3+ ion in V2O3 and LaVO3 as well as in Ti2+ ion in TiO and…

Strongly-correlated crystal-field approach to 3d oxides - the orbital magnetism in 3d-ion compounds
R. J. Radwanski, Z. Ropka
We have developed the crystal-field approach with strong electron correlations, extended to the Quantum Atomistic Solid-State theory (QUASST), as a physically relevant theoretical…
