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

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.

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.

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.

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 ...

Magnetism of $L1_{0}{\rm Fe}_{50-{\rm x}}{\rm Co}_{\rm x}{\rm Pt}_{50}$ Films

IEEE Transactions on Magnetics, 2013
Films of L10-structure Fe50-xCoxPt50 films are synthesized by co-sputtering Fe, Co and Pt on (001) MgO substrates and Si substrates with in-situ heating at 830°C. The nanostructures and magnetic properties of the films are characterized by X-ray diffraction, transmission electron microscopy and SQUID.

ESR Studies on ${\rm Bi}_{0.5}{\rm Ca}_{0.5}{\rm Mn}_{0.95}{\rm TE}_{0.05}{\rm O}_{3}$ (${\rm TE}={\rm V}$, Cu and Zn)

IEEE Transactions on Magnetics, 2011
In this work, the effect of transition element ( TE=V, Cu, and Zn) substitution at Mn site on the electron spin resonance (ESR) of Bi0.5Ca0.5MnO3 was explored. The temperature (T) dependent double integrated intensity (DI) and peak to peak linewidth provide the estimation of charge ordering (CO) temperature TCO, long-range antiferromagnetic (AFM) onset

Correlation Between Enhanced ${\rm T}_{\rm c}$, the Unit Cell Volume and AC Magnetic Shielding in Argon Preheated $({\rm Y}_{1-{\rm x}}{\rm Eu}_{\rm x})({\rm SrBa}){\rm Cu}_{3}{\rm O}_{6+{\rm z}}$

IEEE Transactions on Applied Superconductivity, 2011
We report here on the preparation, X-ray diffraction with Rietveld refinement, resistivity and AC magnetic susceptibility measurements of (Y1-xEux)(SrBa)Cu3O6.94. Each sample was subject to two types of heat treatment: oxygen annealing [O] and argon annealing followed by oxygen annealing [AO].

Magnetostriction and Effective Magnetic Anisotropy of Nanocrystalline ${\rm Ni}_{\rm x}{({\rm Fe}_{0.5}{\rm Co}_{0.5})}_{73.5-{\rm x}}{\rm Cu}_{1}{\rm Nb}_{3}{\rm Si}_{13.5}{\rm B}_{9}$ Alloys

IEEE Transactions on Magnetics, 2011
Ni-content dependence on magnetostriction, effective magnetic anisotropy and initial permeability for as-quenched amorphous Nix(Fe0.5Co0.5)73.5-xNb3Si13.5B9Cu1 (x=0 ~ 30) alloys annealed at 500°C was investigated. XRD showed that all the amorphous samples were partially nanocrystallized after annealing and a two-phase nanocrystalline structure with α ...
