Size-dependent enhancement of passive microwave rectification in magnetic tunnel junctions with perpendicular magnetic anisotropy
A. Sidi El Valli, V. Iurchuk, G. Lezier +11
Spintronic rf detectors were demonstrated, recently, for energy harvesting and wireless communication at low input power. Here we report on the optimization of the rectified output…
CoFeB/MgO/CoFeB structures with orthogonal easy axes: perpendicular anisotropy and damping
H. Głowiński, A. Żywczak, J. Wrona +4
We report on the Gilbert damping parameter , the effective magnetization , and the asymmetry of the -factor in bottom-CoFeB(0.93~nm)/MgO(0.90--1.25~nm)/CoFeB(1.31~…
Influence of intermixing at the Ta/CoFeB interface on spin Hall angle in Ta/CoFeB/MgO heterostructures
Monika Cecot, Lukasz Karwacki, Witold Skowronski +7
We investigate the spin Hall effect in perpendicularly magnetized Ta/Co40Fe40B20/MgO trilayers with Ta underlayers thicker than the spin diffusion length. The crystallographic stru…
Buffer influence on magnetic dead layer, critical current and thermal stability in magnetic tunnel junctions with perpendicular magnetic anisotropy
Marek Frankowski, Antoni Żywczak, Maciej Czapkiewicz +11
We present a thorough research on Ta/Ru-based buffers and their influence on features crucial from the point of view of applications of MTJs, such as critical switching current and…
Spin-torque diode radio-frequency detector with voltage tuned resonance
Witold Skowroński, Marek Frankowski, Jerzy Wrona +3
We report on a voltage tunable radio-frequency (RF) detector based on a magnetic tunnel junction (MTJ). The spin-torque diode effect is used to excite and/or detect RF oscillations…
Influence of MgO tunnel barrier thickness on spin-transfer ferromagnetic resonance and torque in magnetic tunnel junctions
Witold Skowroński, Maciej Czapkiewicz, Marek Frankowski +6
Spin-transfer ferromagnetic resonance (ST-FMR) in symmetric magnetic tunnel junctions (MTJs) with a varied thickness of the MgO tunnel barrier (0.75 nm < < 1.05 nm) is st…
Inductive determination of the optimum tunnel barrier thickness in magnetic tunnelling junction stacks for spin torque memory applications
Santiago Serrano-Guisan, Witold Skowronski, Jerzy Wrona +5
We use pulsed inductive microwave magnetometry to study the precessional magnetization dynamics of the free layer in CoFeB/MgO/CoFeB based magnetic tunnelling junction stacks with…
