Deterministic and stochastic aspects of current-induced magnetization reversal in perpendicular nanomagnets
Giacomo Sala, Jan Meyer, Anne Flechsig +2
We study the incubation and transition times that characterize the magnetization switching induced by spin-orbit torques in nanomagnets with perpendicular anisotropy. We present a…
Orbital Hanle Magnetoresistance in a 3d Transition Metal
Giacomo Sala, Hanchen Wang, William Legrand +1
The Hanle magnetoresistance is a telltale signature of spin precession in nonmagnetic conductors, in which strong spin-orbit coupling generates edge spin accumulation via the spin…
Giant orbital Hall effect and orbital-to-spin conversion in 3d, 5d, and 4f metallic heterostructures
Giacomo Sala, Pietro Gambardella
The orbital Hall effect provides an alternative means to the spin Hall effect to convert a charge current into a flow of angular momentum. Recently, compelling signatures of orbita…
Chiral Coupling between Magnetic Layers with Orthogonal Magnetization
Can Onur Avci, Charles-Henri Lambert, Giacomo Sala +1
We report on the occurrence of strong interlayer Dzyaloshinskii-Moriya interaction (DMI) between an in-plane magnetized Co layer and a perpendicularly magnetized TbFe layer through…
Interplay of voltage control of magnetic anisotropy, spin transfer torque, and heat in the spin-orbit torque switching in three-terminal magnetic tunnel junctions
Viola Krizakova, Eva Grimaldi, Kevin Garello +4
We use three-terminal magnetic tunnel junctions (MTJs) designed for field-free switching by spin-orbit torques (SOTs) to systematically study the impact of dual voltage pulses on t…
Field- and current-driven magnetic domain-wall inverter and diode
Zhaochu Luo, Stefan Schären, Aleš Hrabec +8
We investigate the inversion process of magnetic domain walls (DWs) propagating through synthetic noncollinear magnetic textures, whereby an up/down DW can be transformed into a do…
A two-terminal spin valve device controlled by spin-orbit torques with enhanced giant magnetoresistance
Can Onur Avci, Charles-Henri Lambert, Giacomo Sala +1
We report on the combination of current-induced spin-orbit torques and giant magnetoresistance in a single device to achieve all-electrical write and read out of the magnetization.…
Real-time Hall-effect detection of current-induced magnetization dynamics in ferrimagnets
G. Sala, V. Krizakova, E. Grimaldi +3
Measurements of the transverse Hall resistance are widely used to investigate electron transport, magnetization phenomena, and topological quantum states. Owing to the difficulty o…
Nanomagnonic waveguides based on reconfigurable spin-textures for spin computing
Edoardo Albisetti, Daniela Petti, Giacomo Sala +9
Magnonics is gaining momentum as an emerging technology for information processing. The wave character and Joule heating-free propagation of spin-waves hold promises for highly eff…
