| Abstract Scope |
In this talk, we discuss the spintronic implications of ultra-thin films of Q-carbon, a novel, diamond-like non-equilibrium phase of carbon grown over a large area. Following the Bloch spin wave theory, we demonstrate robust room-temperature ferromagnetism in Q-carbon, with a surprisingly high Curie temperature of ~ 556 K and homogeneous magnetic interactions in the sample. Finally, through ferromagnetic resonance spectroscopy measurements, we show that the spin interactions in Q-carbon are strong and intrinsic to the system, without an exogenous doping with a ferromagnetic ion. We envisage that the intrinsic ferromagnetism in Q-carbon opens a new frontier for carbon-based systems in spintronic devices. |
