Backward volume vs Damon-Eshbach: a travelling spin wave spectroscopy comparison
U. K. Bhaskar, G. Talmelli, F. Ciubotaru +2
We compare the characteristics of electrically transduced Damon-Eshbach (DESWs) and backward volume (BVSWs) configurations within the same, 30 nm thick, ferromagnetic, CoFeB wavegu…
Ferromagnetic resonance study of composite Co/Ni - FeCoB free layers with perpendicular anisotropy
T. Devolder, E. Liu, J. Swerts +6
We study the properties of composite free layers with perpendicular anisotropy. The free layers are made of a soft FeCoB layer ferromagnetically coupled by a variable spacer (Ta, W…
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…
Dynamical influence of vortex-antivortex pairs in magnetic vortex oscillators
Rubén M. Otxoa, Sébastien Petit-Watelot, Mauricio Manfrini +3
We study the magnetization dynamics in a nanocontact magnetic vortex oscillators as function of temperature. Low temperature experiments reveal that the dynamics at low and high cu…
Agility of vortex-based nanocontact spin torque oscillators
M. Manfrini, T. Devolder, Joo-Von Kim +7
We study the agility of current-tunable oscillators based on a magnetic vortex orbiting around a point contact in spin-valves. Theory predicts frequency-tuning by currents occurs a…
