Tailoring the Growth of $I^^{2}$ -Tungsten Using Substrate Bias and Its Effect on FMR-Driven Spin Pumping in $I^^{2}$ -W/Py Heterostructures

Abhay Singh Rajawat, Naim Ahmad, Risvana Nasril +9

$I^^{2}$ -Tungsten ( $I^^{2}$ -W), an A15 cubic phase of tungsten, exhibits a giant spin Hall angle compared to its bcc-phase $I^\pm$ -Tungsten ( $I^\pm$ -W), making high-quality $I^^{2}$ -W films desirabl…
