Ferromagnetic resonance in -Co magnetic composites
Khattiya Chalapat, Jaakko V. I. Timonen, Maija Huuppola +7
We investigate the electromagnetic properties of assemblies of nanoscale -cobalt crystals with size range between 5 nm to 35 nm, embedded in a polystyrene (PS) matrix, at microw…
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…
Magnetic nanocomposites at microwave frequencies
J. V. I. Timonen, R. H. A. Ras, O. Ikkala +5
Most conventional magnetic materials used in the electronic devices are ferrites, which are composed of micrometer-size grains. But ferrites have small saturation magnetization, th…
Unity absorbance layers - optimal design criteria
K. Chalapat, G. S. Paraoanu, Z. Du +3
We present the necessary and sufficient conditions for the unity absorbance of thin planar layers. With a simple structure comprising a double-layer grid, it is shown that zero tra…
Enhancement of sudden death of entanglement for driven qubits
Jian Li, K. Chalapat, G. S. Paraoanu
We study the recently discovered phenomena of sudden death of entanglement for a system of two qubits, each of them independently longitudinally damped by a reservoir and subjected…
Measurement-induced entanglement of two superconducting qubits
Jian Li, K. Chalapat, G. S. Paraoanu
We study the problem of two superconducting quantum qubits coupled via a resonator. If only one quanta is present in the system and the number of photons in the resonator is measur…
