Pozycja Antiferromagnetic ordering of itinerant systems in modified mean field theory(2003) Górski, Grzegorz; Mizia, Jerzy; Kucab, KrzysztofPozycja Correlation Effects in Band Ferromagnetism(cond-mat, 2004) Górski, Grzegorz; Mizia, JerzyWe analyze the influence of different on-site and inter-site interactions on the Curie temperature of transition metal magnetic elements. The numerical calculations show the well known result that the on-site Coulomb repulsion helps ferromagnetism mainly at half-filling of the band, where the 3d elements are antiferromagnetic (Cr, Mn). The inter-site interactions, which in the new approximation decrease the width of the band, favor ferromagnetism at both ends of the band. At the same time they lower the ferromagnetic Curie temperature towards experimental values, removing the paradox which persisted for a long time.Pozycja Interband pairing in extended two- and three-band Hubbard model(2004) Górski, Grzegorz; Mizia, Jerzy; Kucab, KrzysztofPozycja Magnetic Ordering of Itinerant Systems in Modified CPA approximation(2003) Górski, Grzegorz; Mizia, Jerzy; Kucab, KrzysztofPozycja Magnetic ordering of itinerant systems in modified mean field theory: antiferromagnetism(2003) Górski, Grzegorz; Mizia, Jerzy; Kucab, Krzysztof
