TL;DR: In this paper, the I -V characteristics of stacked Josephson junctions were studied under microwave radiation and they were found to exhibit interesting new features which are absent in a single junction.

TL;DR: Ferroelectric and dielectric properties were measured for BaTiO3 thin films prepared by metalorganic chemical vapor deposition which were highly a-axis textured as discussed by the authors, and no ferroelectric hysteresis was observed from the as-deposited Ba TiO3 films on Pt coated MgO.

TL;DR: In this paper, the authors demonstrate that the r.f.m. field produced by a spin valve can be used to reverse the magnetization in a magnetic nanoparticle using a current that specifically excites a uniform spin wave in the spin valve, and this current is swept such that the chirped-frequency generated by the valve matches the angular dependent resonant frequency of the anisotropy-dominated magnetic nanoparticles.

TL;DR: In this paper, postgrowth annealing studies on heteroepitaxial MnAs thin films deposited on GaAs and Si by molecular-beam epitaxy were carried out and the crystal orientation of the MnAs∕Si(001) film changes, and is accompanied by a shift from paramagnetic to ferromagnetic behavior.

TL;DR: In this paper, a high Quality-Factor (high-Q factor) plasmonic resonance with vertically aligned two-dimensional (2D) periodic nanorod arrays is proposed.
