Magnetoelectronic devices

Abstract

Magnetic disk read-heads, magnetic random access memories and spin-dependent transport structures can all be covered by the term magnetoelectronic devices. This review covers spin-dependent transport in magnetic multilayers and aspects of exploitation of this physical property magnetic non-volatile memories (MRAM). The imbalance in the density of states for majority spin-carriers versus minority spin carriers in magnetic materials, triggers spintronic materials and device developments. Such devices are characterized by the fascinating interplay of electronic and magnetic properties.
