Revealing the origin of the vertical hysteresis loop shifts in an exchange biased Co/YMnO bilayer
J. Barzola-Quiquia, A. Lessig, A. Ballestar +4
We have investigated exchange bias effects in bilayers composed by the antiferromagnetic o-YMnO and ferromagnetic Co thin film by means of SQUID magnetometry, magnetoresistance…

Possible superconductivity in multi-layer-graphene by application of a gate voltage
A. Ballestar, P. Esquinazi, J. Barzola-Quiquia +4
The carrier density in tens of nanometers thick graphite samples (multi-layer-graphene, MLG) has been modified by applying a gate voltage () perpendicular to the graphene plan…

Large local Hall effect in pin-hole dominated multigraphene spin-valves
P. K. Muduli, J. Barzola-Quiquia, S. Dusari +4
We report local and non-local measurements in pin-hole dominated mesoscopic multigraphene spin-valves. Local spin-valve measurements show spurious switching behavior in resistance…
