Magnetic remanence at room temperature of archetypal spin interfaces, once paired with a tunable magnetic substrate, opens the possibility to produce future operational spintronic devices. FePc assembled on graphene/Co couples antiferromagnetically with Co up to RT, while CuPc couples ferromagnetically.
These archetypal spin interfaces can be prototypes to demonstrate how antiferromagnetic and/or ferromagnetic coupling can be optimized by selecting the molecular orbital symmetry.
