Electric-field tunable spin diode FMR in patterned PMN-PT/NiFe structures
Sławomir Ziętek, Piotr Ogrodnik, Witold Skowroński +4
Dynamic properties of NiFe thin films on PMN-PT piezoelectric substrate are investigated using the spin-diode method. Ferromagnetic resonance (FMR) spectra of microstrips with vary…
Rectification of radio frequency current in giant magnetoresistance spin valve
Sławomir Ziętek, Piotr Ogrodnik, Marek Frankowski +7
We report on a highly efficient spin diode effect in an exchange-biased spin-valve giant magnetoresistance (GMR) strips. In such multilayer structures, symmetry of the current dist…
Backhopping effect in magnetic tunnel junctions: comparison between theory and experiment
Witold Skowroński, Piotr Ogrodnik, Jerzy Wrona +5
We report on the magnetic switching and backhopping effects due to spin-transfer-torque in magnetic tunnel junctions. Experimental data on the current-induced switching in junction…
Magnetic field sensor with voltage-tunable sensing properties
Witold Skowroński, Piotr Wiśniowski, Tomasz Stobiecki +3
We report on a magnetic field sensor based on CoFeB/MgO/CoFeB magnetic tunnel junctions. By taking advantage of the perpendicular magnetic anisotropy of the CoFeB/MgO interface, th…
Spin transfer torque oscillator based on asymmetric magnetic tunnel junctions
Witold Skowroński, Tomasz Stobiecki, Jerzy Wrona +2
We present a study of the spin transfer torque oscillator based on CoFeB/MgO/CoFeB asymmetric magnetic tunnel junctions. We observe microwave precession in junctions with different…
