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…
Multi-bit MRAM storage cells utilizing serially connected perpendicular magnetic tunnel junctions
Piotr Rzeszut, Witold Skowroński, Sławomir Ziętek +2
Serial connection of multiple memory cells using perpendicular magnetic tunnel junctions (pMTJ) is proposed as a way to increase magnetic random access memory (MRAM) storage densit…
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~…
Current-induced magnetization switching in atom-thick tungsten engineered perpendicular magnetic tunnel junctions with large tunnel magnetoresistance
Mengxing Wang, Wenlong Cai, Kaihua Cao +11
Perpendicular magnetic tunnel junctions based on MgO/CoFeB structures are of particular interest for magnetic random-access memories because of their excellent thermal stability, s…
Understanding stability diagram of perpendicular magnetic tunnel junctions
Witold Skowroński, Maiej Czapkiewicz, Sławomir Ziętek +4
Perpendicular magnetic tunnel junctions (MTJ) with a bottom pinned reference layer and a composite free layer (FL) are investigated. Different thicknesses of the FL were tested to…
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…
