AC losses in a commercial Bi: 2223/Ag tape
(Institute of Physics Publishing, 2009)
We have investigated the effect of temperature, field amplitude, frequency and orientation of the field on AC losses in a commercial Bi:2223/Ag tape. The measurements were performed using an AC susceptometer. The experimental ...
Effects of x in Yb1-xGdxBa2Cu3O7-y samples on c-lattice parameter, activation energy and its magnetic power constant
(Elsevier, 2008)
The Yb1-xGdxBa2Cu3O7-y superconducting samples (x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) which were prepared by solid-state reaction technique were studied to investigate the effect of x on c-lattice parameter, the activation ...
Investigation of effect of x in Yb1-xGdxBa 2Cu3O7-y superconducting structures on upper critical magnetic field and coherence length
(Institute of Physics Publishing, 2009)
The resistivity measurements of the Yb1-xGdxBa 2Cu3O7-y superconducting samples prepared by using the solid-state reaction technique for x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were performed in QD-PPMS system under different ...
Anomalous ferromagnetic behaviour of Y2O3 and CuO nanoparticles in YBa2Cu3Oy superconductor
(Institute of Physics Publishing, 2009)
Anomalous ferromagnetic behaviour of the Y2O3 and CuO components in YBa2Cu3Oy (Y123) was observed after severe reduction of particle size. The particle size reduction was performed in following way: Y2O3, BaCO3 and CuO ...
Influence of annealing temperature on the microstructure and mechanical properties of MgB2
(Institute of Physics Publishing, 2009)
We have investigated the effect of annealing temperature on the microstructure, magnetic and mechanical properties of MgB2 superconducting samples employing X-ray diffraction (XRD), scanning electron microscopy (SEM), ac ...
The influence of substrate temperature on the morphology, optical and electrical properties of thermal-evaporated ZnTe Thin Films
(Elsevier, 2009)
The structural, morphological, optical and electrical properties of ZnTe films deposited by evaporation were investigated as a function of substrate temperature (at -123 and 27 °C) and post-deposition annealing temperature ...
Measurement of Lα, Lβ and Total L X-ray fluorescence cross-sections for some elements with 40≤Z≤53
(Elsevier, 2010)
Lα, Lβ and total L X-ray fluorescence (XRF) cross-sections have been measured for the nine elements (Zr, Nb, Mo, Ag, Cd, In, Sn, Sb and I) using photon energy 5.96 keV. In these the elements, Lα and Lβ spectra were derived ...
AC loss study by AC susceptibility measurement in a commercial Bi:2223/Ag tape prepared by the CTFF method: H ∥ c axis and short specimen
(2010)
The effect of temperature, field amplitude, frequency and orientation of the field on AC losses in a commercial Bi:2223/Ag tape prepared by the continuous filling and forming (CTFF) method has been investigated. The ...
Effects of Meissner surface current on the microwave surface resistance of type-II superconductors
(Elsevier, 2010)
Influence of the Meissner current on the field-induced variations of the microwave (mw) surface resistance in type-II superconductors is demonstrated to be well reproduced by exploiting different critical state models. ...
CdTe thin film solar cells prepared by a low-temperature deposition method
(Wiley, 2010)
Low-temperature vacuum deposition instead of the commonly used vacuum deposition at high substrate temperatures has been applied to prepare high efficiency (CdS/CdTe) solar cells. CdS and CdTe thin films have been subsequently ...
