Effect of Transition Metal Additions on B2-A2 Order-Disorder Phase Transition Temperature in B2 Type FeAl Intermetallic Compounds Yıldırım, Mehmet; Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (null; 2008-12-01)

EFFECT OF GAMMA-IRRADIATION AND SILVER DOPING ON YBCO SUPERCONDUCTOR OZKAN, H; ALBISS, BA; HAMDAN, N; MENARD, A (Springer Science and Business Media LLC, 1994-12-01) The effect of gamma-irradiation and silver doping on the properties of YBCO superconductors has been studied by electrical resistance measurements and x-ray diffraction techniques. The zero-resistance superconducting transition temperature of (YBCO)(1-x)Ag-x systematically increase by about 2 K with an increase of Ag content up to x = 0.04. Further increase in Ag content decreases the transition temperature. The normal-state resistance decreases up to a factor of 3.4 with an increase of Ag content. No signi...
Effect of lithium doping on the properties of Tl-based superconductors Kayed, TS; Ozkan, H; Hasanlı, Nızamı (IOP Publishing, 2001-09-01) The effects of lithium doping on the formation and properties of the T1-based superconductors have been studied. Lithium atoms up to around 3 mol.% have been added to the oxides of nominal composition Tl1.8Ba2Ca2.2Cu3Ox, and the usual solid-state reaction method has been applied. Lithium additions in the range 0.23-0.29 mol.% increase the fraction of the Tl-2223 phase and significantly improve the critical temperature of the samples. Higher amounts of lithium additions diminish the Tl-2223 phase, reduce the...
Effect of thermal neutron irradiation on the pinning properties of TSMG Sm-123 superconductor Topal, U; Dorosinskii, L; Ozkan, H; Yavuz, H (Elsevier BV, 2003-05-01) Changes in the magnetic behavior of melt-textured Sm1.6Ba2.3Cu3.O-3(x) superconductor due to thermal neutron irradiation were investigated at 50 and 77 K. It was observed that J(c) was enhanced up to five times in magnitude after a irradiation fluency of 1.476 x 10(17) cm(-2). We discuss which types of pinning centers can be responsible for the observed behavior.
