Abstract

Spin dynamics and their associated phenomena are emerging as potentially useful candidates for innovation. This thesis investigates two particular cases where spintronics and magnetisation dynamics could be used for novel sensing and computing applications. First, the effect of absorption of hydrogen gas on the Inverse Spin Hall Effect in palladium thin films is investigated for applications in hydrogen gas sensing. Second, the efficacy of using travelling spin waves in magnetic films for hardware implementations of neural network models is investigated. Specifically, the spin-wave delay-line active-ring resonator is used as the substrate to implement the reservoir computing model.
