Enhanced Spectroscopic Insight into Acceptor-Modified Barium Strontium Titanate Thin Films Deposited via the Sol-Gel Method.

In the present paper, composite thin films of barium strontium titanate (BaSrTiO) with an acceptor modifier (magnesium oxide-MgO) were deposited on metal substrates (stainless steel type) using the sol-gel method. The composite thin films feature BaSrTiO ferroelectric solid solution as the matrix and MgO linear dielectric as the reinforcement, with MgO concentrations ranging from 1 to 5 mol%. Following thermal treatment at 650 °C, the films were analyzed for their impedance response.

Study of the Layer-Type BST Thin Film with X-ray Diffraction and X-ray Photoelectron Spectroscopy.

In the present paper, results of X-ray photoelectron studies of electroceramic thin films of barium strontium titanate, BaSrTiO (BST), composition deposited on stainless-steel substrates are presented. The thin films were prepared by the sol-gel method. A spin-coating deposition of BST layers with different chemical compositions was utilized so the layer-type structure of (0-2) connectivity was formed.

Mg Doping Effects on the Structural and Dielectric Properties of CaCuTiO Ceramics Obtained by Mechanochemical Synthesis.

In this study, ceramic CaCuTiO (CCTO) and CaCuMgTiO solid solutions in which 0.1 ≤ x ≤ 0.5 were prepared by the mechanochemical method, realized by a high-energy ball milling technique.

Immittance Studies of BiFeTiO Ceramics.

Results of studies focusing on the electric behavior of BiFeTiO (BFTO) ceramics are reported. BFTO ceramics were fabricated by solid state reaction methods. The simple oxides BiO, TiO, and FeO were used as starting materials.

Magnetoelectric Effect in Ceramics Based on Bismuth Ferrite.

Solid-state sintering method was used to prepare ceramic materials based on bismuth ferrite, i.e., (BiFeO3)1 - x -(BaTiO3) x and Bi1 - x Nd x FeO3 solid solutions and the Aurivillius Bi5Ti3FeO15 compound.
