Doping effects with respect to the electrical properties of morphotropic phase boundary (Bi0.5Na0.5)0.94Ba0.06TiO3 thin films epitaxially grown on CaRuO3 electroded (LaAlO3)0.3(Sr2AlTaO6)0.35 (001) substrates were investigated. Substantial enhancement ferroelectricity and piezoelectricity has been achieved in La+Ce codoped a remanent polarization Pr 29.5 μC/cm2 piezoelectric coefficient d33,f 31 pm/V, whereas Mn doping seems more favorite reduce leakage current by two order magnitude. Both...
Large plate‐like Na 0.5 Bi TiO 3 (NBT) templates have been successfully synthesized from bismuth layer‐structured ferroelectric 4.5 Ti 4 O 15 (NBIT) particles by the topochemical method. Because of highly anisotropic structure, NBIT were first molten‐salt process. After reaction with complementary reactants (Na 2 CO , and ) in NaCl flux, transformed to perovskite NBT templates. The resulting are large shape. Our results also reveal that they more effective inducing grain orientation BNKT‐BT...
Ferroelectric and magnetoresistance heterostructure (Ba,Sr)TiO3/(La,Sr)MnO3 (BST/LSMO) is deposited epitaxially on SrTiO3 (001) substrate by pulse laser deposition. The phase structures of the BST/LSMO are characterized x-ray diffraction. Cross-sectional transmission electron microscope shows a substantial interdiffusision between BST LSMO layers. dielectric properties conductivity measured as function temperature, frequency, electric field. constant dependence field, ε vs E, exhibits strong...
A nanoscaled Ba0.5Sr0.5TiO3 (BST) powder was successfully synthesized using a modified hydrothermal process at low temperature (). By dissolving Ba(OH)2·8H2O and Sr(OH)2·8H2O in deionized water as base solution, nanocrystalline BST can be obtained by mixing an ethanol solution of tetrabutyl titanate with hot stirring. The grain size is close to 17–20 nm, calculated XRD patterns confirmed TEM SEM measurements. perovskite structure core material the self-wrapped non-ferroelectric oxide MgO...
The authors have studied the effects of film thickness on lattice strain and in-plane dielectric ferroelectric properties Ba0.7Sr0.3TiO3 thin films epitaxially grown LaAlO3 (001) single crystal substrates. With increasing from 20to300nm, parameter (a) increased 0.395to0.402nm while out-of-plane (c) remained almost unchanged, which led to an a∕c ratio (tetragonality) changing 0.998 1.012 consequently resulted in a shift Curie temperature 306to360K associated with increase remnant polarization...
The heterostructure of Pt/Ba0.5Sr0.5TiO3/La0.67Sr0.33MnO3 (Pt/BST/LSMO) with the BST thickness ranging from 120 to 550 nm was fabricated by pulsed laser deposition. dielectric constant (e) measured under different electrical fields (E) and frequency (f). A strong dependence value e, e–E e–f were observed, which can be well explained series-capacitor model, based on assumption that electrically consists a 'bulk' layer an interfacial between Pt layers. properties interface obtained. At room...
Lanthanum hydroxychloride is synthesized through a reactive crystallization method at low temperature and with short cycle length in high yields.
Time-of-flight neutron diffraction has been used to investigate deformation behaviors due cyclic loading. A study of 316LN stainless steel shows that in the early stage fatigue life, grain-orientation dependent intergranular stresses develop quickly and oscillate between two extreme states corresponding ends a tensile or compressive half loading cycle. In late stage, strains vanish for tests ending tension remain relatively unchanged compression, which points difference plastic during loadings.
