Abstract
We designed antiferromagnetic spin-1/2 chains in fullerene nanoribbons by introducing extra C<sub>60</sub> cages at one of their edges. The resulting odd number of intermolecular bonds induces an unpaired π-electron and hence a quantized magnetic moment in otherwise nonmagnetic nanoribbons. We further reveal the formation of an antiferromagnetic ground state upon the linear arrangement of spin-1/2 C<sub>60</sub> cages that is insensitive to the specific structural motifs. Janus fullerene nanoribbons may offer an experimentally accessible route to magnetic edge states in low-dimensional carbon nanostructures, possibly serving as a versatile nanoarchitecture for scalable spin-based devices and the exploration of many-body quantum phases.
