The voltage-current characteristics of polycrystalline (Bi,Pb)(2)Sr2Ca2Cu3O10 superconductor were investigated at temperatures from 80 to 105 K under magnetic field up to 0.4 T. In magnetic field considerable broadening in the transition width occurs which depends on the processing conditions and microstructure of the sample. I-V data below T-c were fitted to a power law expression V similar to I-beta to obtain beta. We have found that beta decreases rather rapidly with increase of magnetic field and temperature, in low magnetic fields and at temperatures quite below T-c, respectively. Similar behavior was observed for the variation of the critical current as a function of temperature and magnetic field. The beta values are found to change linearly as a function of critical current at relatively law values of I-c.

Effect of magnetic field and temperature on the voltage-current characteristics of YBCO superconductor Bocuk, H; Albiss, BA; Ercan, I; Ozkan, H; Hasanlı, Nızamı (Springer Science and Business Media LLC, 1996-11-01) Voltage-current characteristics of YBCO superconductor was studied under magnetic field up to 0.4 T at different temperatures below T-c. The critical temperature decreases and the transition width broadens under magnetic field. V-I data below T-c were fitted to a power law expression V similar to I-beta(T,I-B) in which beta(T,B) is found to decrease with increase of magnetic field and temperature, gradually approaching unity as T approaches T-c, being independent of magnetic field. Similarly beta(T,B) appro...
Calculation of Magnetization and Magnetic Susceptibility Close to Magnetic Phase Transitions in (CH3)2NH2FeIIINiII(HCOO)6 and (CH3)2NH2FeIIICuII(HCOO)6 Yurtseven, Hasan Hamit (Springer Science and Business Media LLC, 2020-01-01) We study the temperature and magnetic field dependence of the magnetization (M) and the inverse susceptibility (chi(-1)) in the metal-organic frameworks, in particular, for (CH3)(2)(NH2FeNiII)-Ni-III(HCOO)(6) (DMFeNi) and (CH3)(2)(NH2FeCuII)-Cu-III(HCOO)(6) (DMFeCu) close to their magnetic phase transitions. The Landau phenomenological model is employed to analyze the experimental data for the M(T, H) from the literature and to calculate chi(-1)(T, H) of DMFeNi and DMFeCu. Our results indicate that the ther...
Reflectance spectra and refractive index of a Nd : YAG laser-oxidized Si surface Aygun, G; Atanassova, E; Turan, Raşit; Babeva, T (Elsevier BV, 2005-02-15) The reflectance spectra and refractive index of Nd:YAG laser-oxidized SiO2 layers with thicknesses from 15 to 75 nm have been investigated with respect to the laser beam energy density and substrate temperature. Thickness and refractive index of films have been determined from reflectance measurements at normal light incidence in the spectral range 300-800 nm. It was found that the oxide-growth conditions at higher substrate temperatures and laser powers greater than 3.36 J cm(-2) provides a better film qua...
Morphological evolution of intragranular void under the thermal-stress gradient generated by the steady state heat flow in encapsulated metallic films: Special reference to flip chip solder joints Ogurtani, Tarik Omer; Akyildiz, Oncu (2007-11-30) The morphological evolution of intragranular voids induced by the surface drift-diffusion under the action of capillary forces, electromigration (EM) forces, and thermal stress gradients (TSG) associated with steady state heat flow is investigated in passivated metallic thin films via computer simulation using the front-tracking method. As far as the device reliability is concerned, the most critical configuration for interconnect failure occurs even when thermal stresses are low if the normalized ratio of ...
Annealing effect on the low temperature thermoluminescence properties of GaSe single crystals Isik, M.; Hadibrata, W.; Hasanlı, Nızamı (Elsevier BV, 2014-10-01) Trapping centers in as-grown GaSe single crystals have been investigated by thermoluminescence (TL) measurements in the temperature range of 30-300 K. The analysis of the observed peaks in TL glow curve to determine the activation energies of the associated centers were accomplished using curve fitting, initial rise and peak shape methods. Activation energies of the revealed four trapping centers obtained from various methods were in good agreement with each other on the energy values of 0.14, 0.18, 0.24 an...
