Magnetoresistive detection of perpendicular switching in a magnetic insulator
Silvia Damerio, Achintya Sunil, M. Mehraeen +2
Spintronics offers promising routes for efficient memory, logic, and computing technologies. The central challenge in spintronics is electrically manipulating and detecting magneti…
Chiral Coupling between Magnetic Layers with Orthogonal Magnetization

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…
Spin-orbit torques and magnetotransport properties of -Sn and -Sn heterostructures
Federico Binda, Can Onur Avci, Santos Francisco Alvarado +3
Topological insulators have emerged as an important material class for efficient spin-charge interconversion. Most topological insulators considered to date are binary or ternary c…
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.…
Asymmetric depinning of chiral domain walls in ferromagnetic trilayers
Mark C. H. de Jong, Can Onur Avci, Aleš Hrabec +1
We show that the coupling between two ferromagnetic layers separated by a nonmagnetic spacer can be used to control the depinning of domain walls and induce unidirectional domain w…
Effects of transition-metal spacers on the spin-orbit torques, spin Hall magnetoresistance, and magnetic anisotropy of Pt/Co bilayers
Can Onur Avci, Geoffrey S. D. Beach, Pietro Gambardella
We studied the effect of inserting 0.5 nm-thick spacer layers (Ti, V, Cr, Mo, W) at the Pt/Co interface on the spin-orbit torques, Hall effect, magnetoresistance, saturation magnet…
Origins of the unidirectional spin Hall magnetoresistance in metallic bilayers
Can Onur Avci, Johannes Mendil, Geoffrey S. D. Beach +1
Recent studies evidence the emergence of asymmetric electron transport in layered conductors owing to the interplay between electrical conductivity, magnetization, and the spin Hal…
Co-sputtered PtMnSb thin films and PtMnSb/Pt bilayers for spin-orbit torque investigations
Jan Krieft, Johannes Mendil, Myriam H. Aguirre +7
The manipulation of the magnetization by spin-orbit torques (SOTs) has recently been extensively studied due to its potential for efficiently writing information in magnetic memori…
Magnetoresistance of heavy and light metal/ferromagnet bilayers
Can Onur Avci, Kevin Garello, Johannes Mendil +6
We studied the magnetoresistance of normal metal (NM)/ferromagnet (FM) bilayers in the linear and nonlinear (current-dependent) regimes and compared it with the amplitude of the sp…
Unidirectional spin Hall magnetoresistance in ferromagnet/normal metal bilayers
Can Onur Avci, Kevin Garello, Abhijit Ghosh +3
Magnetoresistive effects are usually invariant upon inversion of the magnetization direction. In noncentrosymmetric conductors, however, nonlinear resistive terms can give rise to…
