Effect of electron correlations in Pd, Ni, and Co monowires
Effect of electron correlations in Pd, Ni, and Co monowires
We investigated the effect of mean-field electron correlations on the band electronic structure of Co, Ni, and Pd ultrathin monatomic nanowires, at the breaking point, by means of density-functional calculations in the self-interaction corrected (SIC) local density approximation (LDA) approach and alternatively by the $\mathrm{LDA}+U$ scheme. We find that adding …
