概要

• 論文の詳細を見る

• The energy-band structures of both paramagnetic (PR) and antiferromagnetic (AF) phases of NdB_6 are calculated by the Korringa-Kohn-Rostoker method within the local-density approximation. In the calculations, 4f-electrons are treated as partially filled core states. The band-structure in the AF phase is satisfactorily explained by a folding procedure of the PR counterpart. The Fermi surfaces in the AF phase consist of two sheets, a multiply-connected hole sheet and a multiply-connected electron one. These Fermi surfaces reasonably reproduce the measured frequency branches of the de Haas-van Alphen effect. From the comparison between the calculated and the observed cyclotron masses, it is pointed out that the mass enhancement due to the f-electrons is negligibly small.
