- •
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 i1" class="mathmlsrc">i1.gif&_user=111111111&_pii=S0169433216319249&_rdoc=1&_issn=01694332&md5=77f08badd5d4e97df18fa508df6c08f5">
