The effect of non‐spherical part of the crystal potential on the band structure of dysprosium metal in the warped muffin‐tin approximation has been studied using the augmented plane wave method. The band structure is not significantly affected by this factor in the present case. The maximum change in energy eigenvalues is 0.002 Ryd. Copyright © 1986 WILEY‐VCH Verlag GmbH & Co. KGaA

The contact conduction electron density in metallic dysprosium has been calculated following the APW formalism and taking into account the effects of correlation and spin-polarization. A comparison of this density with that obtained from the Mössbauer isomer shift measurement has been made. An estimate of Δ〈r2〉, the change in mean square nuclear charge radius between the two levels involved in the γ transition, has been made and compared with those obtained by other workers. © 1991 Indian Academy of Sciences.

Contact charge density in metallic dysprosium

Energy bands of dysprosium have been calculated considering the effects of correlation and spin-polarisation. The exchange and correlation contributions to the spherically symmetric crystalline potential have been taken in the forms suggested by (i) Kohn and Sham and (ii) Overhauser. The exchange and correlation potential of von Barth and Hedin has been used to study the effect of spin-polarisation on the band structures. The resulting bandwidth, density of states, magnetic moment and spin-splitting have been computed and compared with experimental results. Some discrepancies remain; theoretical calculations done so far agree reasonably among themselves, so accurate experimental data are probably called for. © 1984 Indian Academy of Sciences.
