Abstract

We report on a comprehensive study of the electronic and magnetic structure of the striped nickelate La_5/3Sr_1/3NiO₄. 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.
