Suzuki Spinel ferrites are auspicious for the sources of “pure” spin current being developed for spintronic applications, but until recently have exhibited extremely high damping, making these materials unsuitable for coherent spin-current generation. This work demonstrates efficient spin pumping across an epitaxial ferrite/Pt interface, revealing the coexistence of proximity-induced magnetism and spin pumping at these interfaces, and that pumping dominates the microwave-induced voltage. These insights highlight this class of materials as the means to devices based on pure spin currents. [Phys. Rev. Applied 9, 064039] Published Mon Jun 25, 2018
