Magnetic barrier in confined two-dimensional electron gases: Nanomagnetometers and magnetic switches
Magnetic barrier in confined two-dimensional electron gases: Nanomagnetometers and magnetic switches
We investigate the conductance properties of a hybrid ferromagnet-semiconductor structure consisting of a confined two-dimensional electron gas and a transverse ferromagnetic strip on top. Within the framework of the Landauer–Büttiker model, we develop an alternative way to consider magnetic fields. Our method describes devices ranging from a recently realized nanomagnetometer …
