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…
Magneto-optical signal from -based Heusler thin films in MOKE and BLS
Anna Maria Friedel, Nicolas Fermon, Tobias Böttcher +3
-based Heusler compounds offer a versatile, composition-tunable platform for magnonics and spintronics. Among them, the half-metallic is of par…
Epitaxial with intrinsic magnetocrystalline anisotropy as a route to bias-field-free nonlinear half-metal magnonics at the nanoscale
Anna Maria Friedel, Jaafar Ghanbaja, Björn Heinz +5
Half-metallic Heusler compounds like allow to bridge magnonic and spintronic functionality for hybrid unconventional computing approaches with sought-after prop…
Spin-polarization of the electric current in half-metallic CoMnSi Heusler thin films
José Solano Córdova, Anna Maria Friedel, Quentin Rossi +6
Using propagating spin wave spectroscopy we measure the spin wave Doppler shift in patterned MgO/CoMnSi/MgO thin films and determine the degree of spin-polarization of the elec…
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…
