Quantum Hall effect in twisted bilayer graphene.
We address the quantum Hall behavior in twisted bilayer graphene transferred from the C face of SiC. The measured Hall conductivity exhibits the same plateau values as for a commensurate Bernal bilayer. This implies that the eightfold degeneracy of the zero energy mode is topologically protected despite rotational disorder as recently predicted. In addition, an anomaly appears. The densities at...
متن کاملMagnetic bilayer-skyrmions without skyrmion Hall effect
Magnetic skyrmions might be used as information carriers in future advanced memories, logic gates and computing devices. However, there exists an obstacle known as the skyrmion Hall effect (SkHE), that is, the skyrmion trajectories bend away from the driving current direction due to the Magnus force. Consequently, the skyrmions in constricted geometries may be destroyed by touching the sample e...
متن کاملExtraordinary hall balance
Magnetoresistance (MR) effects are at the heart of modern information technology. However, future progress of giant and tunnelling MR based storage and logic devices is limited by the usable MR ratios of currently about 200% at room-temperature. Colossal MR structures, on the other hand, achieve their high MR ratios of up to 10(6)% only at low temperatures and high magnetic fields. We introduce...
متن کاملExtraordinary Hall effect in Fe-Cr giant magnetoresistive multilayers
We show that for giant magnetoresistive Fe-Cr multilayer samples, the scaling law for the extraordinary Hall constant, RS;r n gives unrealistically large values of n(n52.8–3.3) if we use the resistivity r at an external field B50 as done by previous investigators. With B perpendicular to the film plane, the transverse magnetoresistance saturates at B'3 T in the 4.2–300 K temperature range. This...
