Magnetic Properties in ${\rm Li}_{1-{\rm x}}{\rm A}_{\rm x}{\rm NbO}_{3}$ (${\rm A}={\rm Ca}$, Sr, and Ba) and ${\rm LiNbO}_{3-{\rm y}}{\rm M}_{\rm y}$ (${\rm M}={\rm F}$, Cl, and Br) From First-Principles Study

IEEE Transactions on Magnetics, 2011
Based on first-principles study, the magnetic properties of the substitution for Li by A ( A=Ca, Sr, and Ba) and for O by M ( M=F, Cl, and Br) in LiNbO3 have been investigated. These substitutions in LiNbO3 could bring about the magnetic moments, which mainly arise from the s orbital of Nb atoms surrounding the doping element.

Growth of Chemical Solution Deposited $^{\rm TFA}{\rm YBCO}/^{\rm MOD}({\rm Ce},{\rm Zr}){\rm O}_{2}/^{\rm ABAD}{\rm YSZ/SS}$Coated Conductors

IEEE Transactions on Applied Superconductivity, 2009
All chemical solution deposited coated conductors on ABADYSZ/SS tapes with critical current densities at 77 K of Jc = 1.8 MA / cm2 have been obtained. Superconducting YBCO films were grown by the trifluoroacetates route on top of metal organic deposited (Ce, Zr) O2 buffer layers.

Multifunctional Spintronic Material ${\rm Fe}_{\rm x}-{\rm C}_{1-{\rm x}}/{\rm Si}$

IEEE Transactions on Magnetics, 2011
Various carbon based spintronic materials or devices have been made by pulsed laser deposition. It is found that amorphous carbon (a-C) film shows a very large magnetoresistance (MR) of 27% at B=7T and 2 K. It is also found that the a-C/Si heterojunction shows a memory effect at 80 K. A solar cell with structure of Fex-C1-x/Al2O3/Si has been made which

Magnetic Properties of ${[{\rm SnO}_{2}/{\rm Cu}{-}{\rm Zn}\ {\rm ferrite}]}_{\rm n}$ Multilayers

IEEE Transactions on Magnetics, 2012
Multilayers (ML) of [SnO2/Cu-Zn ferrite]n ; were fabricated by rf-sputtering. The effect of number of bilayers, n, on its magnetic properties is studied. The rotational dependence of the ferromagnetic resonance (FMR) parameters depict the anisotropic nature of the ML.

Structural and Magnetic Properties of ${\rm La}_{0.7}{\rm Sr}_{0.3}{\rm Mn}_{1-{\rm x}}{\rm Cr}_{\rm x}{\rm O}_{3}$$({\rm x}\leq 0.5)$

IEEE Transactions on Magnetics, 2010
Magnetic and structural properties of La0.7Sr0.3Mn1-xCrxO3 (x = 0.05, 0.10, 0.20, 0.30, 0.40 and 0.50) have been studied using neutron and x-ray diffraction and magnetic measurements. All samples are found to be of single phase. At 12 K, we find only ferromagnetic ordering for x < 0.30 and coexisting ferromagnetic and antiferromagnetic domains for x ...

Enhanced Ultraviolet Response of ${\rm p}\hbox{-}{\rm Si}/{\rm SiO}_{x}/{\rm i}\hbox{-}{\rm ZnO}/{\rm n}\hbox{-}{\rm ZnO}$ Photodetectors

IEEE Photonics Technology Letters, 2014
Ultraviolet (UV) response of p-Si/i-ZnO/n-ZnO (p-i-n) heterojunction photodetectors (HPDs) was dramatically enhanced by inserting a thin SiOx layer to form a p-Si/SiOx/ i-ZnO/n-ZnO structure. It was found that the leakage current of p-i-n HPDs is largely reduced by about three orders compared with that of conventional p-n HPDs.

Enhancement of ${\rm T}_{\rm c}$, Shielding and Irreversibility Line in Argon Preheated ${\rm Ln}({\rm SrBa}){\rm Cu}_{3}{\rm O}_{6+{\rm z}}$

IEEE Transactions on Applied Superconductivity, 2007
We report here on the preparation, AC magnetic susceptibility and resistivity measurements of LnSrBaCu3O6+z (Ln = rare earth = Eu, Sm, Nd). Each sample was subject to two types of heat treatment: oxygen annealing [O] and argon annealing followed by oxygen annealing [AO].

Correlation Between Enhanced ${\rm T}_{\rm c}$, Orthorhombicity and the Volume of the Unit Cell in Argon Preheated $({\rm Y}_{1-{\rm x}}{\rm Sm}_{\rm x}){\rm SrBaCu}_{3}{\rm O}_{6+{\rm z}}$

IEEE Transactions on Applied Superconductivity, 2009
We report here on the preparation, X-ray diffraction with Rietveld refinement, AC susceptibility measurements and effect of heat treatments in (Y1-xSmx)SrBaCu3O6+z. Each sample was subject to two types of heat treatment: oxygen annealing [O] and argon annealing followed by oxygen annealing [AO].

Study on the Structural, Electrical and Magnetic Properties of the ${\rm Ru}({\rm Sr}_{2-{\rm x}}{\rm Ba}_{\rm x}){\rm GdCu}_{2}{\rm O}_{8\pm{\rm z}}$ System

IEEE Transactions on Applied Superconductivity, 2012
Samples of the Ru(Sr2-xBax)GdCu2O8±z system, with x = 0.00, 0.05, 0.10, 0.15, 0.20, 0.25 and 0.50 were prepared through solid-state reaction at ambient pressure at 980-1025°C. From the X-ray diffraction (XRD) patterns, it was observed that the substitution of Sr by Ba takes place iso-structurally into a tetragonal structure (space group P4/mmm ...
