Scanning hall probe microscopy technique for investigation of magnetic properties
Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor. SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

متن کاملSignatures of spin-charge separation in double–quantum-wire tunneling
We present evidence for spin-charge separation in the tunneling spectrum of a system consisting of two quantum wires connected by a long narrow tunnel junction at the edge of a GaAs/AlGaAs bilayer heterostructure. Multiple excitation velocities are detected in the system by tracing out electron spectral peaks in the conductance dependence on the applied voltage, governing the energy of tunneled...
