In this module, we will discuss how quantum spins and their interactions with the tunneling current systems can be described with model Hamiltonians. We will cover elastic and inelastic scatting processes which lead to magneto-resistive elastic tunneling. Furthermore, we will examine higher order effects and time-dependent effects using a rate equation and Bloch-Redfield model.
