Resumen:
We have performed a partially self-consistent, first-principles calculation of the hyperfine field at a ?+ at the octahedral interstitial site in ferromagnetic nickel. Using a package of programs made available by the Department of Theoretical Chemistry of the University of Mexico, various calculations were performed of the spin-dependent charge density in the central region of a spherically averaged superposition of atomic charge densities. In this way it was found that: (1) The electronic configuration of bulk Ni contains a significant amount of 4p-states, in agreement with other calculations1. (2) The ?+ produces only a weak perturbation on its nearest-neighbor Ni atoms. (3) The hyperfine field at the ?+ is opposite to the bulk magnetization and has the value -590 G, in good agreement with the measured2 value of -641 G. © 1979 North-Holland Publishing Company.
