We study thermal properties of SrMnO3 starting from analysis of the low-energy electronic structure of the Mn4+ ion in oxygen surroundings. As a start point of the studies, simulations of a SrMnO3 unit cell were performed with using the density funct

We have shown that the V4+ ion, realized in PbVO3, with one d electron can have almost non-magnetic ground state under the action of the crystal field in the presence of the spin-orbit coupling. This weakly-magnetic ground state, with low lying cryst

We claim the existence of the f3 (U3+) configuration in UPd2Al3. It is in agreement with inelastic-neutron-scattering (INS) excitations and is consistent with the trivalent neptunium configuration in NpPd2Al3. We have derived set of CEF parameters fo

We claim that the observed large reduction of the effective moment and the drastic violation of the Curie-Weiss law in Na2V3O7 (Phys. Rev. Lett. 90 (2003) 167202) is caused by conventional crystal-field interactions and the intra-atomic spin-orbit co

We present the calculated low-energy electronic structure, in the meV energy scale, of Sr 2 RuO 4 that is associated with the single-ion states of the Ru 4+ ion. For description of the d electrons of the Ru 4+ ion we take into account the orbital deg

The description of basic experiments of the rare-earth hard magnetic materials, high-field magnetization curves on single-crystalline samples of Ho2Co17 and Nd2Fe14B is reviewed with the aim to derive parameters physically relevant on atomic scale. T
