Material Specification for Bi:2212; [Bi-Sr-Ca-Cu-O]
Process: Floating Zone
Notes: The authors cite A.M. Balbashov et al., 1989 Proc. of European Conf. on High Tc Thin Films and Single Crystals, Ustron Poland 95-106, and summarize the procedure as follows. "The Bi(2212) melt textured samples were made by floating zone melting technique... The samples show a high degree of texture along all three axes. Neutron scattering reveals a misorientation along the c-axis of not more than 3°. The sample was cut into a rectangular shape with dimensions 3 mm x 1 mm x 3 mm along a, b, and c, respectively."

Critical Temperature (K) |
82 ± 2 |
Measurement Method: Vibrating sample magnetometer
"... magnetization measurements (were made) with a vibrating sample magnetometer... Critical current density within the a,b plane (was) obtained from magnetization with a dB/dt of 12 mT/s (corresponding to 0.1 µV/cm)... We determine B(T) at which the current density has a value of 10 A/cm
2. Form the electric field used for this measurement the resistivity is obtained. Measurements were made in the resistivity range from 10
-1 µΩ·cm to 10
-5 µΩ·cm at fields up to 12 T... Irreversibility field... (was determined) with a criterion of 10
-3 µΩ·cm..."
