Abstract
Data prove the existence of the phase via x-ray diffraction, energy-dispersive x-ray spectroscopy, and electronic transport. The material is then evaluated with regard to spin transport through the use of non-local spin valves (NLSVs). The provided data can be used to determine the Elliot-Yafet parameters for defects and phonons that describe spin relaxation in this metal.
