Interface-Controlled Spin-Orbit Torques in Rare-Earth Synthetic Ferrimagnets Probed by Sagnac Magneto-Optics and Harmonic Hall Measurements
Akilan K, Koral Aykin, Jose-Luis Ampuero +6
Spin-orbit torque (SOT) provides an efficient route for manipulating magnetization in spintronic devices, and its accurate quantification is essential. Here, we investigate Co/Gd-b…
Unconventional views on orbitronics supported by experimental results
Melissa Yactayo, A. Pezo, J. L. Ampuero +9
Emerging orbitronics assumes long-range orbital current transport, analogous to spin currents. However, recent theory and experiments challenge this view, showing rather local char…
