The effective-field study of a mixed spin-1 and spin-5/2 Ising ferrimagnetic system
(2009)
An effective-field theory with correlations is developed for a mixed spin-1 and spin-5/2 Ising ferrimagnetic system on the honeycomb (?=3) and square (?=4) lattices in the absence and presence of a longitudinal magnetic ...
Determination of levitation force and pinning properties of (Sm123) 1-x(Yb211) x bulk superconductor depending on Yb211 doping ratio
(Wiley, 2009)
The vertical force density curves of (Sm123) 1-x(Yb211)x high temperature superconductor (HTS) samples prepared by a meltpowder-melt-growth technique were measured during vertical and lateral traverses in zero field cooling ...
The polarization of X-rays and magnetic photoionization cross-sections for L3 sub-shell
(Elsevier, 2009)
The alignment of atoms with inner-shell vacancies resulting from ionization by photons was investigated by measuring the anisotropic emission of L shell X-ray lines. The X-ray line intensities were measured using an Si(Li) ...
Changing the conductivity type of ultrasonically sprayed ZnO thin films: comparison of the effects of Li, N, and B dopants
(Springer, 2023)
ZnO is a material widely used in technological applications. However, the difficulty of preparing p-type ZnO creates a bottleneck for developing ZnO-based devices. In this study, Li, N, and B-doped ZnO thin films were ...
Determination of mass attenuation coefficients, effective atomic and electron numbers for some natural minerals
(Elsevier, 2009)
The total mass attenuation coefficients (?m) for SiO2 {Quartz (1 1 0 1), Quartz (1 1 0 0) and Quartz (0 0 0 1)}, KAlSi3O8 {Orthoclase (0 1 0), Orthoclase (1 0 0)}, CaSO4·2H2O (gypsum), FeS2 (pyrite) and Mg2Si2O6 (pyroxene) ...
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 ...
Coupled-channel and distorted-wave Born approximation analyses for 25.1 MeV and 32.5 MeV energies of p- 40Ar inelastic scattering
(Springer, 2008)
The optical model parameters, the coupled-channel parameters and excitation mode ?2 , ?3 and ?5 deformation parameters corresponding to the best fit to the experimental differential cross-sections and the analyzing powers ...
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 ...
