ABSTRACT

This chapter presents a summary of some of the most relevant

studies of shot noise in inorganic single-tunnel-barrier spintronic

devices. Although we shall deal mainly with charge-related shot

noise, we shall see that spin degree of freedom could influence

the shot noise through spin flip scattering or spin accumulation.

We first briefly consider shot noise in Al2O3-based MTJs which

were historically the first type of MTJs discovered. The main deal

of analysis will be dedicated to shot noise in MgO-based MTJs

which revolutionized spintronics since 2004.We shall concludewith

discussion of recent proposals and attempts to observe pure spin

shot noise in MTJs.
