OCV hysteresis in nickel metal hydride batteries
NiMH batteries exhibit a hysteresis, or path dependence, regarding the rest voltage of the system. Depending on charge/discharge history of the battery the rest voltage will be... -
Superconductivity and magnetism in novel iron-based superconductors
Magnetism and superconductivity compete and coexist in many of the high temperature superconductors, and the newly discovered iron arsenides are no exception. Muon-spin rotation... -
Investigation of magnetic defects in exfoliated graphite
Graphene has recently received widespread attention, after the discovery of its stability as a 2Dcrystal at ambient conditions and thanks to a wealth of possible applications....
