Revealing nanoscale disorder in W/CoFeB/MgO ultra-thin films using domain wall motion
Johannes Wilhelmus van der Jagt, Vincent Jeudy, André Thiaville +11
Disorder in ultra-thin magnetic films can significantly hinder domain wall motion. One of the main issues on the path towards efficient domain wall based devices remains the charac…
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…
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…
Thickness-dependence of the Dzyaloshinskii-Moriya interaction in Co2FeAl ultrathin films: effects of the annealing temperature and the heavy metal material
M. Belmeguenai, Y. Roussigné, S. M. Chérif +8
Interfacial Dzyaloshinskii-Moriya interaction (iDMI) has been investigated in Co2FeAl (CFA) ultrathin films of various thicknesses (0.8 nm<tCFA<2 nm) grown on Si substrates, using…
Investigation of the interfacial Dzyaloshinskii-Moriya interaction sign in Ir/Co2FeAl systems by Brillouin light scattering

Interfacial Dzyaloshinskii-Moriya interaction (iDMI) in interlayer exchange coupled (IEC) Pt/CoFeB(1.12 nm)/Ru/CoFeB(1.12 nm) systems have…
Anisotropic Dzyaloshinskii-Moriya Interaction in ultra-thin epitaxial Au/Co/W(110)
Lorenzo Camosi, Stanislas Rohart, Olivier Fruchart +8
We have used Brillouin Light Scattering spectroscopy to independently determine the in-plane Magneto-Crystalline Anisotropy and the Dzyaloshinskii-Moriya Interaction (DMI) in out-o…
Current-induced skyrmion generation and dynamics in symmetric bilayers
Ales Hrabec, Joao Sampaio, Mohamed Belmeguenai +7
Magnetic skyrmions are textures behaving as quasiparticles which are topologically different from other states. Their discovery in systems with broken inversion symmetry sparked th…
Anomalous polarization conversion in arrays of ultrathin ferromagnetic nanowires
Andrey A. Stashkevich, Yves Roussigné, Alexander N. Poddubny +7
We study optical properties of arrays of ultrathin nanowires by means of the Brillouin scattering of light on magnons. We employ the Stokes/anti-Stokes scattering asymmetry to prob…
