93Nb NMR in the incommensurate and quasicommensurate phases of barium sodium niobate.
sodium niobate (BSN) between 300 and 650 K. The spectra are inhomogeneously broadened in the incommensurate (1) phase between Tr=580 K and Tc =540 K as well as in the quasicommensurate (QC) phase below Tc. However, the observed line shapes do not exhibit the characteristics of the lines for other lq and 2q modulated incommensurate materials. The temperature dependence of the observed line shape...
متن کاملStructural, dielectric and optical properties of barium strontium sodium niobate (Sr0.7Ba0.3)2NaNb5O15 single crystals
Barium strontium sodium niobate (Sr0.7Ba0.3)2NaNb5O15 (SBNN70) crystals were grown by the Czochralski method. X-ray energy dispersive spectrometry showed that SBNN70 crystals have a stoichiometric composition nearly identical to the starting materials. X-ray diffraction of crushed powder indicated that the SBNN70 crystals are orthorhombic with a = 1.2748 nm, b = 1.1402 nm and c = 0.3898 nm. The...
متن کاملAnalyses of elastic waves in Aluminum/Barium sodium niobate and Quartz/Epoxy phononic structures
This study was aimed at using the theory for two-dimensional phononic crystal consisting of materials with general anisotropy to calculate the band gaps phenomena in Aluminum/Barium sodium niobate (Y-cut) with hexagonal lattice and Quartz/Epoxy with square lattice phononic structures. Wave propagation properties of solids in which the periodic modulation occurs along the bounding surface has be...
متن کاملSBN60, strontium-barium niobate at 100 K
The title compound, Sr0.6Ba0.4Nb2O6 (strontium barium niobium oxide), belongs to the group of strontium-barium niobates with varying composition of Sr and Ba. Their general formula can be written as Sr x Ba1 - x Nb2O6. Below the Curie temperature, T c , these materials indicate ferroelectric properties. The Curie temperature for SBN60 is equal to 346±0.5 K so the structure is in the ferroelectr...
متن کاملLow-loss planar optical waveguides in strontium barium niobate crystals formed by ion-beam implantation.
Planar optical waveguides have been formed in strontium barium niobate single crystals by either proton or heliumion implantation. The profiles of the ordinary and the extraordinary refractive indices are deduced from dark-line mode spectroscopy. Optical barriers with depths to Deltan(e) = 2.6% for protons and Deltan(e) = 5.5% for helium are obtained. By proton implantation we find a very low i...
