Abstract

The trend in the lattice parameters of the actinide nitride series is interpreted in terms of metallic 5f-5f and covalent cation 5f anion 2p contributions to the calculated equations of state. The lattice parameters are obtained from self-consistent LMTO, RLMTO and spin polarized LMTO calculations. Particularly large magnetovolume effects were found for NpN - AmN. Spin - orbit splitting also increased the calculated volumes of NpN - AmN and the density of states at the Fermi level was found to be predominantly of 5f-5/2 character for the paramagnetic ground states of UN-AmN.
