Field-induced transition from room-temperature ferromagnetism to diamagnetism in proton-irradiated fullerene.
Room-temperature ferromagnetism in proton-irradiated C60 fullerene is demonstrated. The ferromagnetism turns into diamagnetism intrinsic to the fullerene as the magnetic field increases above a critical field.
