Spin-orbit torque switching in 2D ferromagnet / topological insulator heterostructure grown by molecular beam epitaxy
Thomas Guillet, Regina V. Galcera, Juan F. Sierra +4
Topological insulators (TIs) are a promising class of materials for manipulating the magnetization of an adjacent ferromagnet (FM) through the spin-orbit torque (SOT) mechanism. Ho…
Resolving spin currents and spin densities generated by charge-spin interconversion in systems with reduced crystal symmetry
Lorenzo Camosi, Josef Svetlik, Marius V. Costache +7
The ability to control the generation of spins in arbitrary directions is a long-sought goal in spintronics. Charge-to-spin interconversion (CSI) phenomena depend strongly on symme…
Van der Waals heterostructures for spintronics and opto-spintronics
Juan F. Sierra, Jaroslav Fabian, Roland K. Kawakami +2
The large variety of 2D materials and their co-integration in van der Waals (vdW) heterostructures enable innovative device engineering. In addition, their atomically-thin nature p…
Heat dissipation in few-layer MoS2 and MoS2/hBN heterostructure
Alois Arrighi, Elena del Corro, Daniel Navarro Urrios +8
State-of-the-art fabrication and characterization techniques have been employed to measure the thermal conductivity of suspended, single-crystalline MoS2 and MoS2/hBN heterostructu…
Absence of magnetic-proximity effect at the interface of BiSe and (Bi,Sb)Te with EuS
A. I. Figueroa, F. Bonell, M. G. Cuxart +5
We performed x-ray magnetic circular dichroism (XMCD) measurements on heterostructures comprising topological insulators (TIs) of the (Bi,Sb)(Se,Te) family and the magnetic…
Control of spin-orbit torques by interface engineering in topological insulator heterostructures
Frédéric Bonell, Minori Goto, Guillaume Sauthier +6
(BiSb)Te topological insulators (TIs) are gathering increasing attention owing to their large charge-to-spin conversion efficiency and the ensuing spin-orbit to…
