Magnetic Properties of Multilayer ${[({\rm FePt})_{\rm x}/{\rm Os}]}_{\rm n}$ Films

IEEE Transactions on Magnetics, 2010
Multilayer [(FePt)x/Os]n films (with x being thickness in nm; Os with a fixed thickness 5 nm; n being the number of layers) have been deposited by ion-beam sputtering. Spacer layer was found to have substantial effects on the multilayers to exhibit different magnetic properties and microstructure.

Permeability Dispersion and Magnetic Loss of ${\rm Fe}/{\rm Ni}_{\rm x}{\rm Zn}_{1-{\rm x}}{\rm Fe}_{2}{\rm O}_{4}$ Soft Magnetic Composites

IEEE Transactions on Magnetics, 2012
Fe/NixZn1-xFe2O4 ( x=0.1, 0.3, 0.5, 0.7, 0.9) soft magnetic composites were prepared by the chemical co-precipitation method. The effect of Ni content on the magnetic properties was discussed. The results of SEM, EDS and X-ray diffraction analysis indicate that an uniform and dense Ni-Zn ferrite was coated on the surface of bared Fe.

Structural and Scintillation Properties of Cerium-Doped ${\rm Ba}_{{}_{1- \rm x}}{\rm La}_{{}_{\rm x}}{\rm Cl}_{{}_{2+ \rm x }}$ Ceramics

IEEE Transactions on Nuclear Science, 2008
A series of cerium-doped compounds with the composition Ba1-xLaxCl2+x and 0 < x < 0.5 have been prepared in ceramic form. We find from the powder X-ray diffraction patterns that the compounds adopt the cubic fluorite structure for 0.05 < x 0.34. Samples with x~ 0.2 are translucent.

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].

MIM Capacitors Based on ${\rm ZrTiO}_{\rm x}/{\rm BaZr}_{\rm y}{\rm Ti}_{\rm 1-y}{\rm O}_{3}$ Featuring Record-Low VCC and Excellent Reliability

IEEE Electron Device Letters, 2013
Perovskite-based BaZryTi1-yO3 (BZTO) (y=0.6) with partial crystallization has been found to possess a rather high- κ value of 48.6 and positive quadratic voltage coefficient of capacitance (VCC). Through stacking BZTO and ZrTiOx as laminate dielectric, metal-insulator-metal capacitors using VCC canceling effect advance frontiers by exhibiting a record ...

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 ...

Dependence of Epitaxial ${\rm Ba}{({\rm Fe}_{1-{\rm x}}{\rm Co}_{\rm x})}_{2}{\rm As}_{2}$ Thin Films Properties on ${\rm SrTiO}_{3}$ Template Thickness

IEEE Transactions on Applied Superconductivity, 2011
In our previous report, we demonstrated the growth of high-quality epitaxial Co-doped Ba(Fe1-xCox)2As2 (Ba-122) thin films using single crystalline SrTiO3 (STO) templates on (La,Sr)(Al,Ta)O3 (LSAT) substrates with pulsed laser deposition (PLD). Here, we report the dependence of the structural and superconducting properties of Ba-122 thin films on STO ...

Effect of Resolidification Conditions on ${\rm Bi}_{2}{\rm Sr}_{2}{\rm CaCu}_{2}{\rm O}_{\rm x}/{\rm Ag/AgMg}$ Coil Performance

IEEE Transactions on Applied Superconductivity, 2009
The performance of Bi2Sr2CaCu2Ox (Bi2212) wires is very sensitive to the heat treatment conditions, and in particular to the conditions immediately after partial-melting. In this paper, the effect of solidification conditions on Bi2212/Ag/AgMg coil performance is investigated using a split melt process.

An ${({\rm Al}_{\rm x}{\rm Ga}_{1-{\rm x}})}_{2}{\rm O}_{3}$ Metal-Semiconductor-Metal VUV Photodetector

IEEE Sensors Journal, 2011
The authors report the conversion of AlGaN epitaxial layer into (AlxGa1-x)2O3 thin film by furnace oxidation at high temperature in oxygen containing ambient. A vacuum-ultraviolet (AlxGa1-x)2O3 photodetector (PD) was also fabricated. It was found that external quantum efficiency of the fabricated PD measured at 220 nm was 30%.

Study of ${\rm Sm}_{\rm x}{\rm Zr}_{1-{\rm x}}{\rm O}_{\rm y}$ Buffer Layer and Its Effects on YBCO Properties

IEEE Transactions on Applied Superconductivity, 2007
Biaxially textured SmxZr1-xOy (SZO) thin films have been grown directly on an ion beam assisted deposited (IBAD) MgO template, without using an intermediate homoepitaxial MgO layer. SZO buffer layers were deposited using reactive magnetron sputtering of a Sm (50 at.%)-Zr (50 at.%) alloy target.
