Steven Louis PhD of Oakland University

Spintronic devices exploit electron spin to enable faster, smaller, and more energy-efficient electronics. This talk introduces foundational spintronic mechanisms through two key materials systems: yttrium iron garnet (YIG), which supports propagating spin waves, and magnetic tunnel junctions (MTJs), which store information in magnetization states. The wave-like behavior of spin in YIG offers a platform for analog logic and wave-based computing, while MTJs form the core of magnetic random-access memory (MRAM), a non-volatile memory integrated with standard CMOS. The presentation also examines spin torque nano-oscillators, which convert direct current into microwave-frequency signals via magnetization precession. These phenomena are governed by the Landau-Lifshitz-Slonczewski equation, which captures the dynamic interaction between spin, current, and external fields. Together, these examples illustrate how spintronic principles can be harnessed to develop memory and logic technologies that transcend conventional charge-based electronics.
