Relationship between growth speed and magnetic properties in Bi-2212/Ag textured composites
In this paper, the measured magnetic properties of Bi2Sr2CaCu2O x /3 wt.% Ag textured composite materials prepared by a LFZ melting technique at different growth speeds (5, 15, 30, and 60 mm/h) are presented. X-ray diffraction patterns have shown that Bi-2212 phase is the major one in all cases. The...

| Sumario: | In this paper, the measured magnetic properties of Bi2Sr2CaCu2O x /3 wt.% Ag textured composite materials prepared by a LFZ melting technique at different growth speeds (5, 15, 30, and 60 mm/h) are presented. X-ray diffraction patterns have shown that Bi-2212 phase is the major one in all cases. The magnetization measurements have been carried out as a function of the magnetic field up to 10 kOe. J c values, calculated using Bean¿s model, indicate that the growth speeds have a significant effect on J c . It has been found that the maximum critical current density, 4.42×105 A/cm2 at 10 K, has been obtained for the 15 mm/h grown sample. |
