Transmission electron microscopy and ferromagnetic resonance investigations of tunnel magnetic junctions using Co2MnGe Heusler alloy as magnetic electrodes
M. Belmeguenai, C. Genevois, F. Zighem +6
HRTEM, nano-beam electronic diffraction, energy dispersive X-rays scanning spectroscopy, Vibrating Sample Magnetometry (VSM) and FerroMagnetic Resonance (FMR) techniques are used i…
Magnetization dynamics in Co2O3$/Co tunnel junctions grown on different substrates
M. Belmeguenai, H. Tuzcuoglu, F. Zighem +7
We study static and dynamic magnetic properties of Co2MnGe (13 nm)/Al2O3 (3 nm)/Co (13 nm) tunnel magnetic junctions (TMJ), deposited on various single crystalline substrates (a-pl…
Structural and magnetic properties of Co2MnSi thin films
Mohamed Belmeguenai, Fatih Zighem, Damien Faurie +4
Co2MnSi (CMS) films of different thicknesses (20, 50 and 100 nm) were grown by radio frequency (RF) sputtering on a-plane sapphire substrates. Our X-rays diffraction study shows th…
Structural, static and dynamic magnetic properties of CoMnGe thin films on a sapphire a-plane substrate
Mohamed Belmeguenai, Fatih Zighem, Thierry Chauveau +6
Magnetic properties of CoMnGe thin films of different thicknesses (13, 34, 55, 83, 100 and 200 nm), grown by RF sputtering at 400°C on single crystal sapphire substrates, were stud…
Evidence for triplet superconductivity in Josephson junctions with ferromagnetic CuMnAl-Heusler barriers
D. Sprungmann, K. Westerholt, H. Zabel +2
We have studied Josephson junctions with barriers prepared from the Heusler compound CuMnAl. In the as-prepared state the CuMnAl layers are non ferromagnetic and the critic…
Josephson tunnel junctions with ferromagnetic $\Fe_{0.75}\Co_{0.25}$ barriers
D. Sprungmann, K. Westerholt, H. Zabel +2
Josephson tunnel junctions with the strong ferromagnetic alloy $\Fe_{0.75}\Co_{0.25}$ as the barrier material were studied. The junctions were prepared with high quality down to a…
