Abstract

We report on a comprehensive study of the electronic and magnetic structure of the striped nickelate La 5/3 Sr 1/3 NiO 4 . The investigation is carried out using band structure calculations based on the density functional theory. A magnetic structure compatible with experiment is obtained from spin-polarized calculations within the generalized gradient approximation (GGA), whereas inclusion of a local Coulomb interaction in the LDA+ U framework results in a different ground state. The influence of the various interaction parameters is discussed in detail.
