"quantum orbital Hall effect in tuneable transition metal oxide strontium ruthenate... causes electrons to move as determined by orbital angular momentum... defect engineering simultaneously boosts both orbital Hall conductivity and orbital Hall angle, a stark contrast to conventional spin-based systems... scattering processes that typically degrade performance, extend orbital angular momentum lifetime, thereby enhancing orbital current... tailored conductivity modulation yielded 3X improved switching energy efficiency"
