Structural tunability in metamaterials
Mikhail Lapine, David Powell, Maxim Gorkunov +3
We propose a novel approach for efficient tuning of the transmission characteristics of metamaterials through a continuous adjustment of the lattice structure, and confirm it exper…
Interplay of inequivalent atomic positions in resonant x-ray diffraction of Fe3BO6
G Beutier, E Ovchinnikova, S P Collins +8
'Forbidden' Bragg reflections of iron orthoborate Fe3BO6 were studied theoretically and experimentally in the vicinity of the iron K edge. Their energy spectra are explained as res…
Superconductivity at 36 K in beta-Fe1.01Se with the compression of the interlayer separation under pressure
S. Medvedev, T. M. McQueen, I. Trojan +8
In this letter, we report that the superconductivity transition temperature in beta-Fe1.01Se increases from 8.5 to 36.7 K under applied pressure of 8.9 GPa. It then decreases at hi…
Ferroelectric ordering in chiral smectic C^* liquid crystals determined by nonchiral intermolecular interactions
M. A. Osipov, M. V. Gorkunov
General microscopic mechanism of ferroelectric ordering in chiral smectic C* liquid crystals is considered. It is shown that if the mesogenic molecules have a sufficiently low symm…
Tunability of wire-grid metamaterial immersed into nematic liquid crystal
M. V. Gorkunov, M. A. Osipov
We propose electrically tunable hybrid metamaterial consisting of special wire grid immersed into nematic liquid crystal. The plasma-like permittivity of the structure can be subst…
Structural and transport properties of GaAs/delta<Mn>/GaAs/InxGa1-xAs/GaAs quantum wells
B. A. Aronzon, M. V. Kovalchuk, E. M. Pashaev +11
We report results of investigations of structural and transport properties of GaAs/Ga(1-x)In(x)As/GaAs quantum wells (QWs) having a 0.5-1.8 ML thick Mn layer, separated from the QW…
