Abstract

We present a review of some of our recent experimental work on hybrid ferromagnet/semiconductor devices in which 2D electrons propagate through magnetic barriers, periodic magnetic modulations, and random magnetic fields.

Bibliographical note

Funding Information:
Hybrid semiconductor/ferromagnet devices show a wide range of interesting new transport properties. Many are semi-classical in origin and persist up to room temperature. We have recently obtained MR values up to ∼50% at room temperature for large amplitude barriers. These devices have potential as magnetic field sensors, memory or logic elements, and nanomagnetometers. The financial support of the EPSRC (UK) is gratefully acknowledged.
