Entropy-Assisted Nanosecond stochastic operation in perpendicular superparamagnetic tunnel junctions
Lucile Soumah, Louise Desplat, Nhat-Tan Phan +7
We demonstrate a good agreement between mean dwell times measured in 50~nm diameter, perpendicularly magnetized superparamagnetic tunnel junctions (SMTJ), and theoretical predictio…
Evidence for spin current driven Bose-Einstein condensation of magnons
B. Divinskiy, H. Merbouche, V. E. Demidov +9
The quanta of magnetic excitations - magnons - are known for their unique ability to undergo Bose-Einstein condensation at room temperature. This fascinating phenomenon reveals its…
Ultrafast amplification and non-linear magneto-elastic coupling of coherent magnon modes in an antiferromagnet
D. Bossini, M. Pancaldi, L. Soumah +6
We investigate the role of domain walls in the ultrafast magnon dynamics of an antiferromagnetic NiO single crystal in a pump-probe experiment with variable pump photon energy. Ana…
Optically-induced frequency up-conversion of the ferromagnetic resonance in an ultrathin garnet
Lucile Soumah, Davide Bossini, Abdelmadjid Anane +1
We perform ultrafast pump-probe measurements on a nanometer-thick crystalline Bi-doped yttrium iron garnet film with perpendicular magnetic anisotropy. Tuning the photon energy of…
Emission of coherent propagating magnons by insulator-based spin-orbit torque oscillators
M. Evelt, L. Soumah, A. B. Rinkevich +8
We experimentally demonstrate generation of coherent propagating magnons in ultra-thin magnetic-insulator films by spin-orbit torque induced by dc electric current. We show that th…
Ultra-low damping insulating magnetic thin films get perpendicular
Lucile Soumah, Nathan Beaulieu, Lilia Qassym +7
A magnetic material combining low losses and large Perpendicular Magnetic Anisotropy (PMA) is still a missing brick in the magnonic and spintronic fields. We report here on the gro…
