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…
Symmetry Breaking by Interfacial Dead Layers: Observation of Forbidden Self-Induced Spin-Orbit Torque in Symmetric Ferromagnets
Athira Ravindran K, Raghvendra Posti, Manish Kumar Mohanta +8
Conventionally, spin-orbit torques (SOTs) in ferromagnets require heavy-metal layers or engineered structural asymmetry to break inversion symmetry. In this work, we report the obs…
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…
RF field characterization and rectification effects in spin pumping and spin-torque FMR for spin-orbitronics
Melissa Yactayo, Michel Hehn, J. -C. Rojas-Sánchez +1
Quantifying spin-orbital-to-charge conversion efficiency is crucial for spin-orbitronics. Two widely used methods for determining these efficiencies are based on ferromagnetic reso…
Spin current symmetries generated by GdFeCo ferrimagnet across its magnetisation compensation temperature
Héloïse Damas, Michel Hehn, Juan-Carlos Rojás-Sanchez +1
Ferrimagnets, composed of antiferromagnetically coupled magnetic sublattices whose net magnetisation can be tuned by temperature, offer a unique platform for probing the symmetry o…
