Temperature dependence of microwave voltage emission associated to spin-transfer induced vortex oscillation in magnetic tunnel junction
P. Bortolotti, A. Dussaux, J. Grollier +7
The temperature dependence of a vortex-based nano-oscillator induced by spin transfer torque (STVO) in magnetic tunnel junctions (MTJ) is considered. We obtain emitted signals with…
Anisotropic magneto-Coulomb effect versus spin accumulation in a ferromagnetic single-electron device
A. Bernand-Mantel, P. Seneor, K. Bouzehouane +4
We investigate the magneto-transport characteristics of nanospintronics single-electron devices. The devices consist of single non-magnetic nano-objects (nanometer size nanoparticl…
Nanoscale ferroelectric manipulation of magnetic flux quanta
Arnaud Crassous, Rozenn Bernard, Stéphane Fusil +7
Using heterostructures that combine a large-polarization ferroelectric (BiFeO3) and a high-temperature superconductor (YBa2Cu3O7-δ), we demonstrate the modulation of the supercondu…
Electrical spin injection and detection in Germanium using three terminal geometry
A. Jain, L. Louahadj, J. Peiro +12
In this letter, we report on successful electrical spin injection and detection in \textit{n}-type germanium-on-insulator (GOI) using a Co/Py/AlO spin injector and 3-te…
Hysteretic magnetic pinning and reversible resistance switching in High-Tc superconductor/ferromagnet multilayers
C. Visani, P. J. Metaxas, A. Collaudin +6
We study a high-TC superconducting (YBa2Cu3O7-d) / ferromagnetic (Co/Pt multilayer) hybrid which exhibits resistance switching driven by the magnetic history: depending on the dire…
Identification and selection rules of the spin-wave eigen-modes in a normally magnetized nano-pillar
Vladimir V. Naletov, Grégoire De Loubens, Gonçalo Albuquerque +12
We report on a spectroscopic study of the spin-wave eigen-modes inside an individual normally magnetized two layers circular nano-pillar (PermalloyCopperPermalloy) by means o…
