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…
Type-II-like ultrafast demagnetization behavior in NiCo2O4 thin films
Ryunosuke Takahashi, Kaede Yamada, Harjinder Singh +10
Rare-earth-ferrimagnetic oxides are emerging as attractive platforms for investigating ultrafast spin dynamics. Here, we study the photoinduced magnetization dynamics of epitaxial…
Epitaxial Ni/Cu Superlattice Nanowires with Atomically Sharp Interfaces for Spin Transport
Janez Zavašnik, Sama Derakshan-Nejad, Maryam Ghaffari +6
The importance of microstructure increases when decreasing the size of an object to the nanoscale, along with the complexity of controlling it. For instance, it is particularly com…
Single-Shot Magnetization Reversal in Ferromagnetic Spin Valves Enabled via Heat Control
Kazuaki Ishibashi, Junta Igarashi, Alberto Anadón +7
We study laser induced ultrafast magnetization reversal in a ferromagnetic spin valve by comparing the effects of direct laser excitation and ultrashort hot electron pulses. A wedg…
All-optical helicity-dependent switching in NiCoO thin films
Ryunosuke Takahashi, Yann Le Guen, Suguru Nakata +8
All-optical switching (AOS) involves manipulating magnetization using only pulsed laser, presenting a promising approach for next-generation magnetic recording devices. NiCo2O4 (NC…
Light-induced torque in ferromagnetic metals via orbital angular momentum generated by photon-helicity
Koki Nukui, Satoshi Iihama, Kazuaki Ishibashi +7
We investigated photon-helicity-induced magnetization precession in CoPt alloy thin films. In addition to field-like torque, attributable to magnetic field generation…
