Abstract :

Employing the first-principles calculations with onsite Coulomb interaction, the electronic structure of monolayer WS2 doped substitutionally with 3d transition metals is investigated. While neither W vacancies nor strain induces spin polarization, we demonstrate an unprecedented tendency to extended moment formation under doping. The extended magnetic moments are characterized by dopant specific spin density patterns with rich structural features involving the nearest neighbor W and S atoms.
