Solid-State Thin-Film Sensors Based on Chalcogenide Materials Obtained by Planar Technology and Pulsed Laser Deposition

Methods of silicon planar technology and pulsed laser deposition were applied to fabricate fully solid-state chemical sensors for determining ions of copper, lead, cadmium, thallium, and also sulfide and chloride ions on the basis of thin chalcogenide films as ion-sensitive membranes.     

Freedom from the interpolation property for tense calculi associated with Ershov spaces

We study into the question whether calculi associated with Ershov topological spaces possess Craig’s interpolation property.

Giant Magnetic Field Induced Effects in the Second-Harmonic Generation in a Planar Anisotropic Ta/Co/Pt Structure

JETP Letters - Magnetic field induced effects in the second-harmonic generation in a thin asymmetric Ta/Co/Pt trilayer film with in-plane magnetic anisotropy are investigated. It is shown that the...     

Magnetization-induced third harmonic generation in magnetic nanogranular films: Correlation with giant magnetoresistance

Magnetization-induced third harmonic (TH) generation was observed in magnetic nanostructures—nanogranular Co_xAg_{1? x} films—possessing giant magnetoresistance (GMR). The magnetization-induced contribution to the TH intensity was studied as a function of the concentration of a magnetic component (cobalt) in the films. Magnetic contrast of the TH intensity was found to correlate with the GMR coefficient: both parameters simultaneously reach extremum in the range of cobalt concentrations x～0.3–0.35.     

A Modal Logic Based on Linearly Ordered f-Spaces

A modal logic associated with the -spaces introduced by Ershov is examined. We construct a modal calculus that is complete w.r.t. the class of all strictly linearly ordered -frames, and the class of all strictly linearly ordered -frames.     

Enhancement of the nonlinear effects in composite plasmonic nanoparticles

Features of the second- and third-order nonlinear effects in composite plasmonic core/shell nanoparticles placed into a polymer matrix are investigated. Resonant enhancement of the effective third-order susceptibility is observed, as well as the appearance of a coherent magnetization-induced component of the second harmonic.
