Ultrathin bismuth-yttrium iron garnet films with tunable magnetic anisotropy
Hanchen Wang, William Legrand, Davit Petrosyan +7
We report on the epitaxial growth of nm-thick films of bismuth-substituted yttrium iron garnet (BiYIG) by high-temperature off-axis radio-frequency magnetron sputtering. We demonst…

Orbital Pumping in Ferrimagnetic Insulators
Hanchen Wang, Min-Gu Kang, Davit Petrosyan +5
We report the detection of pure orbital currents generated by both coherent and thermal magnons in the magnetic insulator Bi-doped yttrium iron garnet (BiYIG). The pumping of orbit…

Competing Ordinary and Hanle Magnetoresistance in Pt and Ti Thin Films
Sebastian Sailler, Giacomo Sala, Denise Reustlen +5
One of the key elements in spintronics research is the spin Hall effect, allowing to generate spin currents from charge currents. A large spin Hall effect is observed in materials…
