Dynamic phase diagrams of a mixed spin-1 and spin-5/2 Ising system in an oscillating magnetic field
(2009)
We study the nonequilibrium aspects of the kinetics of a mixed spin-1 and spin-5/2 Ising system, including the biquadratic nearest-neighbor pair interaction (K) and the crystal-field interaction (D), under the presence of ...
Investigation of some superconducting properties of ytterbium diffusion-doped YBa2Cu3O7-x superconductors
(Elsevier, 2008)
The effect of Yb diffusion on structural evolution and superconducting properties of YBa2Cu307-x (Y123) prepared in the bulk polycrystalline form were studied. The ytterbium (Yb) diffusion in superconducting Y123 ceramic ...
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 ...
