Nanocontact vortex oscillators based on CoMnGe pseudo-spin valves
Jérémy Létang, Claudia de Melo, Charles Guillemard +9
We present an experimental study of vortex dynamics in magnetic nanocontacts based on pseudo spin valves comprising the CoMnGe Heusler compound. The films were grown by molecul…
Engineering CoMnAlSi Heusler compounds as a model system to correlate spin polarization, intrinsic Gilbert damping and ultrafast demagnetization
C. Guillemard, W. Zhang, G. Malinowski +8
Engineering of magnetic materials for developing better spintronic applications relies on the control of two key parameters: the spin polarization and the Gilbert damping responsib…
Ultra-low magnetic damping in Co 2 Mn-based Heusler compounds: promising materials for spintronic
C Guillemard, S. Petit-Watelot, L. Pasquier +8
The prediction of ultra-low magnetic damping in Co 2 MnZ Heusler half-metal thin-film magnets is explored in this study and the damping response is shown to be linked to the underl…
Chaos in Magnetic Nanocontact Vortex Oscillators
Thibaut Devolder, Damien Rontani, Sébastien Petit-Watelot +10
We present an experimental study of spin-torque driven vortex self-oscillations in magnetic nanocontacts. We find that above a certain threshold in applied currents, the vortex gyr…
Co/Ni multilayers for spintronics: high spin-polarization and tunable magnetic anisotropy
S. Andrieu, T. Hauet, M. Gottwald +13
In this paper we analyze in details the electronic properties of (Co/Ni) multilayers, a model system for spintronics devices. We use magneto-optical Kerr (MOKE), spin-polarized pho…
Long range phase coherencein double barrier magnetic tunnel junctions with large thick metallic quantum well
B. S. Tao, H. X. Yang, Y. L. Zuo +11
Double barrier heterostructures are model systems for the study of electron tunneling and discrete energy levels in a quantum well (QW). Until now resonant tunneling phenomena in m…
