Magnetic-Adsorbate-Induced Spin Polarization in Carbon Materials —Two Fe Atoms on Planar C₁₀ and C₁₀H₈—

Abstract

Here we consider a nanoscale material consisting of two Fe atoms sitting on a planar C₁₀ cluster. On the basis of the density functional theory (DFT), we demonstrate how it is feasible to induce spin polarization on an initially nonmagnetic carbon material by introducing magnetic adsorbates, and how the presence of hydrogen reduces the induced polarization.
