Effect of Transport Current on the Pinning Induced Magnetostriction of Type-II Superconductors
(Polish Acad Sciences Inst Physics, 2008)
Teorik olarak taşıma akımının ve uygulanan manyetik alanın tip-II süperiletkenlerin manyetostriksiyonu üzerindeki etkisini araştırdık. Bir süperiletken levha örneğinin manyetostriktif tepkisini incelemek için, mevcut ...
Improvement of superconducting properties of MgB2 by changing the argon ambient pressure and sintering conditions
(Institute of Physics Publishing, 2009)
We have investigated various characteristic properties depending on sintering conditions of MgB2 samples prepared by the standard solid state reaction method. It is inferred from experimental results that the crystallinity ...
Dependency of c-lattice parameter, activation energy and its magnetic power constant on x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconductors
(Elsevier, 2008)
To investigate the effect of x on c-lattice parameter, the activation energy, and the magnetic power constant of activation energy, the nominal composition of Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, ...
Gadolinium diffusion-doping for enhancing activation energy in superconducting YBa2Cu3O7-x
(Elsevier, 2008)
The resistance transitions of Gd-diffused polycrystalline Y123 samples have been measured as a function of temperature and magnetic field. It is deduced from experimental results that the activation energy increases when ...
Investigation of the dependency of the upper critical magnetic field on the content x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting structures
(Elsevier, 2008)
The Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were prepared by using the solid-state reaction technique. Resistivity measurements of the samples were performed in QD-PPMS ...
Determination of the effective atomic numbers and electron densities for YBaCuO superconductor in the range 59.5-136 keV
(Elsevier, 2008)
The effective atomic numbers and electron densities of YBa2Cu3O7-? superconductor at 59.5, 65.2, 77.1, 94.6, 122 and 136 keV were calculated by using the measured mass attenuation coefficients. Measurements were made by ...
Role of coexistence of superconductivity and paramagnetism in magnetostriction of high-T c superconductors
(Springer, 2008)
Total magnetostriction in the superconducting state for high-T c superconductors has been separated into critical state and paramagnetic components in terms of a H (x) dependent magnetic flux density. We show that the ...
Modeling of normal-state like contribution on the pinning induced magnetostriction
(Elsevier, 2008)
To describe the change of the sign of the magnetostriction at the field close to the upper critical field, Bc2, which were observed in some magnetostriction measurements carried out on the type-II superconductors, theoretical ...
Calculation of radiation doses to human organs from consumption of marine fish
(Inderscience Publishers, 2008)
In the present work, radiation doses are estimated from the analysis of 40K, 137Cs, 226Ra and 228Ra radionuclides in marine fish of the Bay of Bengal, accumulated in ten different human organs: red marrow, lung, thyroid, ...
An extended model for coexistence of superconductivity and paramagnetism in high-Tc superconductors
(2008)
In the present work, the total magnetization in superconducting state is separated into critical state and paramagnetic components in terms of an H(x)-dependent magnetic flux density. Utilizing this model, we reproduce ...
