Spiking Dynamics in Dual Free Layer Perpendicular Magnetic Tunnel Junctions
Louis Farcis, Bruno Teixeira, Philippe Talatchian +8
Spintronic devices have recently attracted a lot of attention in the field of unconventional computing due to their non-volatility for short and long term memory, non-linear fast r…
Direct observation of the perpendicular shape anisotropy and thermal stability of p-STT-MRAM nano-pillars
Trevor P. Almeida, Steven Lequeux, Alvaro Palomino +6
Perpendicular shape anisotropy (PSA) offers a practical solution to downscale spin-transfer torque Magnetic Random-Access Memory (STT-MRAM) beyond the sub-20 nm technology node whi…
Observation of magnetic helicoidal dichroism with extreme ultraviolet light vortices
Mauro Fanciulli, Matteo Pancaldi, Emanuele Pedersoli +17
We report on the experimental evidence of magnetic helicoidal dichroism, observed in the interaction of an extreme ultraviolet vortex beam carrying orbital angular momentum with a…
Magnetization reversal driven by spin-transfer-torque in perpendicular shape anisotropy magnetic tunnel junctions
N. Caçoilo, S. Lequeux, B. M. S. Teixeira +6
The concept of perpendicular shape anisotropy spin-transfer torque magnetic random-access memory (PSA-STT-MRAM) consists in increasing the storage layer thickness to values compara…
Realizing an Isotropically Coercive Magnetic Layer for Memristive Applications by Analogy to Dry Friction
Marco Mansueto, Antoine Chavent, Stephane Auffret +8
We investigate the possibility of realizing a spintronic memristive device based on the dependence of the tunnel conductance on the relative angle between the magnetization of the…
Steady State and Dynamics of Joule Heating in Magnetic Tunnel Junctions Observed via the Temperature Dependence of RKKY Coupling
A. Chavent, C. Ducruet, C. Portemont +5
Understanding quantitatively the heating dynamics in magnetic tunnel junctions (MTJ) submitted to current pulses is very important in the context of spin-transfer-torque magnetic r…
Respective influence of in-plane and out-of-plane spin-transfer torques in magnetization switching of perpendicular magnetic tunnel junctions
A. A. Timopheev, R. Sousa, M. Chshiev +2
The relative contributions of in-plane (damping-like) and out-of-plane (field-like) spin-transfer-torques in the magnetization switching of out-of-plane magnetized magnetic tunnel…
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…
Quasi ballistic magnetization reversal
H. W. Schumacher, C. Chappert, R. C. Sousa +2
We demonstrate a quasi ballistic switching of the magnetization in a microscopic mag-neto resistive memory cell. By means of time resolved magneto transport we follow the large ang…
Phase Coherent Precessional Magnetization Reversal in Micro-scopic Spin Valve Elements
H. W. Schumacher, C. Chappert, P. Crozat +5
We study the precessional switching of the magnetization in microscopic spin valve cells induced by ultra short in-plane hard axis magnetic field pulses. Stable and highly efficien…
