Challenges in orbital current-driven domain wall motion in light metal/ferrimagnet heterostructures
Min-Gu Kang, Jaerin Kim, Benjamin J. Jacot +2
Recent advances in spintronics suggest that orbital Hall currents generated by charge injection in light metals can provide nonequilibrium angular momentum without relying on stron…
Charge-to-spin conversion in epitaxial and polycrystalline Bi and Bi/Ag layers
Federica Nasr, Emir Karadža, Santos F. Alvarado +9
Bi is predicted to be an efficient generator of spin-orbit torques (SOTs), with charge-to-spin conversion efficiency comparable to those of prototypical heavy metals, such as Ta, W…
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…
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…
Mitigation of Gilbert Damping in the CoFe/CuOx Orbital Torque System
Shilei Ding, Hanchen Wang, William Legrand +2
Charge-spin interconversion processes underpin the generation of spin-orbit torques in magnetic/nonmagnetic bilayers. However, efficient sources of spin currents such as 5d metals…
Lattice-tunable substituted iron garnets for low-temperature magnonics
William Legrand, Yana Kemna, Stefan Schären +7
The synthesis of nm-thick epitaxial films of iron garnets by physical vapor deposition has opened up exciting opportunities for the on-chip generation and processing of microwave s…
Orbital Torque in Rare-Earth Transition-Metal Ferrimagnets
Shilei Ding, Min-Gu Kang, William Legrand +1
Orbital currents have recently emerged as a promising tool to achieve electrical control of the magnetization in thin-film ferromagnets. Efficient orbital-to-spin conversion is req…
Spin-orbit torques and magnetization switching in Gd/Fe multilayers generated by current injection in NiCu alloys
Federica Nasr, Federico Binda, Charles-Henri Lambert +3
Light transition metals have recently emerged as a sustainable material class for efficient spin-charge interconversion. We report measurements of current-induced spin-orbit torque…
Magnetic properties and domain structure of ultrathin yttrium iron garnet/Pt bilayers
Johannes Mendil, Morgan Trassin, Qingqing Bu +10
We report on the structure, magnetization, magnetic anisotropy, and domain morphology of ultrathin yttrium iron garnet (YIG)/Pt films with thickness ranging from 3 to 90 nm. We fin…
Antiferromagnetic multi-level memory cell
V. Schuler, K. Olejnik, X. Marti +9
Antiferromagnets (AFs) are remarkable magnetically ordered materials that due to the absence of a net magnetic moment do not generate dipolar fields and are insensitive to external…
