Low-Noise Nanoscale Vortex Sensor for Out-of-Plane Magnetic Field Detection
Ajay Jha, Alvaro Palomino, Stéphane Auffret +4
This study investigates a vortex sensor based on a nanoscale (sub-100 nm) magnetic tunnel junction (MTJ) with a strong shape anisotropy, designed for sensitivity to the out-of-plan…
Analog and digital phase modulation of spin torque nano-oscillators
A. Litvinenko, P. Sethi, C. Murapaka +6
Spin torque nano-oscillators (STNO) are nanoscale devices with wide band frequency tunability. Their multifunctional RF properties are well suited to define novel schemes for wirel…
Second order anisotropy contribution in perpendicular magnetic tunnel junctions
A. A. Timopheev, R. Sousa, M. Chshiev +2
Magnetoresistance loops under in-plane applied field were measured on perpendicularly magnetized magnetic tunnel junction (pMTJ) pillars with nominal diameters ranging from 50 to 1…
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…
Temperature dependence of the emission linewidth in MgO-based spin torque nano-oscillators
J. F. Sierra, M. Quinsat, U. Ebels +8
Spin transfer driven excitations in magnetic nanostructures are characterized by a relatively large microwave emission linewidth (10 -100 MHz). Here we investigate the role of ther…
