High-Field and Light-Dependent Magnetization Provides Evidence for Coexisting Granular Superconductivity and Superparamagnetism in Nitrogen-Doped Diamond

E. Osmic, J. Barzola-Quiquia, S. Winnerl +3

We investigated the field-, temperature-, and time-dependent magnetic moment of a nitrogen-doped type Ib diamond in darkness and under monochromatic light with a low laser intensit…
