Gate-controlled skyrmion and domain wall chirality
Charles-Elie Fillion, Johanna Fischer, Raj Kumar +14
Magnetic skyrmions are localized chiral spin textures, which offer great promise to store and process information at the nanoscale. In the presence of asymmetric exchange interacti…
Effect of Chiral Damping on the dynamics of chiral domain walls and skyrmions
C. K. Safeer, Mohamed-Ali Nsibi, Jayshankar Nath +6
Friction plays an essential role in most physical processes that we experience in our everyday life. Examples range from our ability to walk or swim, to setting boundaries of speed…
Mechanism of Spin-Orbit Torques in Platinum Oxide Systems
Jayshankar Nath, Alexandru Vladimir Trifu, Mihai Sebastian Gabor +16
Spin-Orbit Torque (SOT) Magnetic Random-Access Memories (MRAM) have shown promising results towards the realization of fast, non-volatile memory systems. Oxidation of the heavy-met…
Penetration depth of Cooper pairs in the IrMn antiferromagnet
R. L. Seeger, G. Forestier, O. Gladii +8
Suppression of superconductivity due to the proximity effect between a superconductor and a ferromagnet can be partially alleviated when a Cooper pair simultaneously samples differ…
Control of skyrmion chirality in Ta/FeCoB/TaOx trilayers by TaOx oxidation and FeCoB thickness
Raj Kumar, Charles-Elie Fillion, Bertrand Lovery +10
Skyrmions are magnetic bubbles with nontrivial topology envisioned as data bits for ultrafast and power-efficient spintronic memory and logic devices. They may be stabilized in hea…
Realizing an Isotropically Coercive Magnetic Layer for Memristive Applications by Analogy to Dry Friction
Marco Mansueto, Antoine Chavent, Stephane Auffret +8
We investigate the possibility of realizing a spintronic memristive device based on the dependence of the tunnel conductance on the relative angle between the magnetization of the…
Mapping different skyrmion phases in double wedges of Ta/FeCoB(tFeCoB)/Ta(tTa)Ox
Titiksha Srivastava, Willy Lim, Isabelle Joumard +3
Skyrmions are chiral magnetic textures that have immense potential for applications in spintronic devices. However, their formation is quite challenging and necessitates a subtle b…
Unraveling the influence of electronic and magnonic spin current injection near the magnetic ordering transition of IrMn metallic antiferromagnets
O. Gladii, L. Frangou, G. Forestier +6
Although spin injection at room temperature in an IrMn metallic antiferromagnet strongly depends on the transport regime, and is more efficient in the case of magnonic transport, i…
Temperature dependence of the emission linewidth in MgO-based spin torque nano-oscillators
J. F. Sierra, M. Quinsat, U. Ebels +8
Spin transfer driven excitations in magnetic nanostructures are characterized by a relatively large microwave emission linewidth (10 -100 MHz). Here we investigate the role of ther…
Anomalous magnetic field dependence of the thermodynamic transition line in the isotropic superconductor (K,Ba)Bi03
S. Blanchard, T. Klein, J. Marcus +6
Thermodynamic (specific heat, reversible magnetization, tunneling spectroscopy) and transport measurements have been performed on high quality (K,Ba)BiO single crystals. The te…
A Bragg glass phase in the vortex lattice of a type II superconductor
T. Klein, I. Joumard, S. Blanchard +4
Although crystals are usually quite stable, they are sensitive to a disordered environment: even an infinitesimal amount of impurities can lead to the destruction of the crystallin…
