Orbital torque and efficient magnetization switching using ultrathin Co|Al light-metal interfaces: Experiments and modeling
N. Sebe, A. Pezo, S. Krishnia +5
The emergence of the orbital degree of freedom in modern orbitronics offers a promising alternative to heavy metals for the efficient control of magnetization. In this context, ide…
Neuromorphic weighted sums with magnetic skyrmions
Tristan da Câmara Santa Clara Gomes, Yanis Sassi, Dédalo Sanz-Hernández +7
Integrating magnetic skyrmions into neuromorphic computing could help improve hardware efficiency and computational power. However, developing a scalable implementation of the weig…
Quantitative analysis of vectorial torques in thin 3d Co ferromagnet using orbital-spin conversion
B. Bony, S. Krishnia, Y. Xu +6
Recent findings in orbitronics pointed out large current-induced torques originating, in the current understanding, from incident orbital currents. These are generated by orbital R…
Alternative harmonic detection approach for quantitative determination of spin and orbital torques
Y. Xu, B. Bony, S. Krishnia +6
In this study, the spin-orbit torque (SOT) in light metal oxide systems is investigated using an experimental approach based on harmonic Hall voltage techniques in out-of-plane (OO…
Large Chiral Orbital Texture and Orbital Edelstein Effect in Co/Al Heterostructure
Sergey A. Nikolaev, Mairbek Chshiev, Fatima Ibrahim +6
Recent experiments by S. Krishnia et al., Nano Lett. 23, 6785 (2023) reported an unprecedentedly large enhancement of torques upon inserting thin Al layer in Co/Pt heterostructure…
