The role of oxygen vacancies and their location in the magnetic properties of Ce1-xCuxO2-delta nanorods
(Royal Soc Chemistry, 2015-01-01)
Ceria (CeO2) is a promising dilute magnetic semiconductor. Several studies report that the intrinsic and extrinsic structural defects are responsible for room temperature ferromagnetism in undoped and transition metal doped ...
Correlation between photoluminescence and structural defects in Ca 1+x Cu 3 - X Ti 4 O 12 systems
(2013-01-01)
Ca1+xCu3-xTi4O12 powders were synthesized by a conventional solid-state reaction. X-ray diffraction (XRD) was performed to verify the formation of cubic CaCu3Ti4O 12 (CCTO) and orthorhombic CaTiO3 (CTO) phases at long ...
Dielectric relaxation and relaxor behavior in bilayered perovskites
(American Institute of Physics (AIP), 2009-06-29)
Sr(0.5)Ba(0.5)Bi(2)Nb(2)O(9) ferroelectric ceramics exhibit a complex dielectric behavior, showing typical relaxor behavior. The relaxation processes are described by the Cole-Cole model [K. S. Cole and R. H. Cole, J. Chem. ...
Structural and dielectric properties of relaxor Sr0.5Ba 0.5Bi2Nb2O9 ceramic
(2010-03-01)
Sr0.5Ba0.5Bi2Nb2O 9 ceramic was prepared by a conventional solid state reaction method and studied using X-ray powder diffraction and dielectric measurements. At room temperature, an orthorhombic structure was confirmed ...
Electrical transport properties and complex impedance investigation of Fe 3+ and La 3+ co-doping (Pb,Sr)TiO 3 thin films
(2018-10-01)
This work investigates the impact of Fe 3+ and La 3+ co-doping on the structural, electrical transport and dielectric relaxation properties of PST thin films. XRD and Raman spectroscopy data show that the Fe 3+ and La 3+ ...
Magnetic properties and triple valence fluctuations of iron in PrSr2Fe3O9-delta

Periodic study on the structural and electronic properties of bulk, oxidized and reduced SnO2(110) surfaces and the interaction with O-2
(Elsevier Science BvAmsterdamHolanda, 2002)
A relationship between structural and electronic order-disorder effects and optical properties in crystalline TiO2 nanomaterials
(Royal Soc Chemistry, 2015-01-01)
The focus of this paper is on the analysis of the structural and electronic order-disorder effects at long, medium and short ranges of titanium dioxide (TiO2) nanoparticles synthesized by the sol-gel process followed by ...
