文摘

•: Fe atoms are successfully isolated at various C, N, O, Cl, S and F shells in graphene to preserve the high-spin state.
•: The graphene embedding with the Fe₃/F₆ core/shell cluster has a large magnetic moment for 7.24 μB.
•: The Curie temperature of Fe₂/Cl₄ and Fe₂/S₄ core/shell systems are about $T_{C}^{M F A}$ = 475 K and 479 K, respectively.
