Probing the Dzyaloshinskii-Moriya interaction in CoFeB ultrathin films using domain wall creep and Brillouin light spectroscopy
R. Soucaille, M. Belmeguenai, J. Torrejon +7
We have characterized the strength of the interfacial Dyzaloshinskii-Moriya interaction (DMI) in ultrathin perpendicularly magnetized CoFeB/MgO films, grown on different underlayer…

Time-resolved spin-torque switching in MgO-based perpendicularly magnetized tunnel junctions
T. Devolder, Joo-Von Kim, F. Garcia-Sanchez +5
We study ns scale spin-torque-induced switching in perpendicularly magnetized tunnel junctions (pMTJ). Although the switching voltages match with the macrospin instability threshol…

A skyrmion-based spin-torque nano-oscillator
F. Garcia-Sanchez, J. Sampaio, N. Reyren +2
A model for a spin-torque nano-oscillator based on the self-sustained oscillation of a magnetic skyrmion is presented. The system involves a circular nanopillar geometry comprising…
