Properties of Thin Films of Barium–Strontium Titanate Solid Solutions by Induced Piezoelectric Effect

Piezoelectric effect equations have been derived by linearizing the nonlinear equations of state of a thin film existing in a paraelectric phase in the presence of an external electrical field (induced piezoelectric effect). The behavior of the piezoelectric and elastic constants of thin films of a solid barium–strontium titanate solution BST065 (x = 0.65) in a planar field at different misfit strain values has been studied numerically.     

Nonlinear Optical Properties of Nanosized Rare-Earth–Doped Strontium Barium Niobate Ceramics

Nanosized, undoped and rare-earth–doped Sr_0.5Ba_0.5Nb₂O₆ (SBN) ceramic systems were synthesized by an aqueous organic gel route. The precursor gel on calcinations at 800°C for 2 hr produces undoped and rare-earth–doped SBN systems of pure tungsten bronze lattice structure. These systems have been characterized for their structure by XRD, SEM, and TEM. The nonlinear absorption behavior of the undoped and rare-earth–doped SBN ceramic systems was investigated by use of the open-aperture Z-scan technique using 532 nm, 5 ns laser pulses. The authors found that these materials are potential optical limiters at this excitation wavelength.

Extraordinary Magnetic Properties of Ca1–xEuxS and Sr1–xEuxS Solid Solutions

The electron paramagnetic resonance (EPR) spectra and the stationary magnetic susceptibility are investigated for Ca_1–x Eu _x S and Sr_1–x Eu _x S solid solutions (0.00005 < x < 0.0032). The EPR spectrum of Eu²⁺ in both matrices contains a wide structureless line in addition to the narrow lines of the superfine structure characteristic of ions with high local symmetry. Because of the extraordinary temperature dependence of this line in CaS:Eu, it is associated with strongly interacting magnetic centers, namely, exchange-coupling pairs and chains or more complex clusters of magnetic ions. At the same time, the dependence of the stationary magnetic susceptibility in the temperature range 4.2–50 K has no peculiarities for CaS:Eu and SrS:Eu and obeys the Curie law.

Kinetics and Phase Transformations during the Decomposition of Supersaturated Solid Solutions of Magnesium in Mg–Dy–Sm Alloys

Kinetics and phase transformations are studied for the previously unconsidered decomposition of supersaturated solid solution in magnesium-based alloys Mg–Dy–Sm. The decomposition of solid solution slows when there is an increase in % Dy: % Sm ratio in the alloys. Mg–Sm and Mg–Dy alloys grow harder when Dy and Sm are added to them, respectively. Products of decomposition in ternary Mg–Dy–Sm alloys are the same as in binary alloys Mg–Dy and Mg–Sm but contain combinations of Dy and Sm.
