Exchange stiffness in ultrathin perpendicularly-magnetized CoFeB layers determined using spin wave spectroscopy
T. Devolder, J. -V. Kim, L. Nistor +3
We measure the frequencies of spin waves in nm-thick perpendicularly magnetized FeCoB systems, and model the frequencies to deduce the exchange stiffness of this material in the ul…
Modulating spin transfer torque switching dynamics with two orthogonal spin-polarizers by varying the cell aspect ratio
B. Lacoste, M. Marins de Castro, T. Devolder +9
We study in-plane magnetic tunnel junctions with additional perpendicular polarizer for subnanosecond-current-induced switching memories. The spin-transfer-torque switching dynamic…
Spatially periodic domain wall pinning potentials: Asymmetric pinning and dipolar biasing
P. J. Metaxas, P. -J. Zermatten, R. L. Novak +9
Domain wall propagation has been measured in continuous, weakly disordered, quasi-two-dimensional, Ising-like magnetic layers that are subject to spatially periodic domain wall pin…
Direct Observation of Massless Domain Wall Dynamics in Nanostripes with Perpendicular Magnetic Anisotropy
Jan Vogel, Marlio Bonfim, Nicolas Rougemaille +8
Domain wall motion induced by nanosecond current pulses in nanostripes with perpendicular magnetic anisotropy (Pt/Co/AlO) is shown to exhibit negligible inertia. Time-resolved…
Dynamic binding of driven interfaces in coupled ultrathin ferromagnetic layers
P. J. Metaxas, R. L. Stamps, J. P. Jamet +4
We demonstrate experimentally dynamic interface binding in a system consisting of two coupled ferromagnetic layers. While domain walls in each layer have different velocity-field r…
Spin injection in Silicon at zero magnetic field
L. Grenet, M. Jamet, P. Noé +7
In this letter, we show efficient electrical spin injection into a SiGe based \textit{p-i-n} light emitting diode from the remanent state of a perpendicularly magnetized ferromagne…
