Material Specification for PbSr:2213; [Pb-Sr-Y(Ca)-Cu-O]
Process: Solid State Reaction
Notes: The authors cite M.M. Lukina et al., Superconductivity, Vol. 3, 2767 (1990), and summarize the procedure as follows. "Using the flux growth method from the non-stoichiometric melts with an excess of PbO, SrO and CuO we were able to obtain... large high quality single crystals having almost a perfect cubic shape. All measurements reported in the present paper have been carried out on the... single crystals with Tc = 80 K and characteristic dimensions of 0.6x0.6x0.5mm3."

Measurement Method: SQUID magnetometer
"We have studied temperature, time and field dependences of the magnetization M on a MPM2 Quantum Design SQUID-magnetometer with the scan length 3 cm corresponding to the field homogeneity better than 0.05%."
Cautions: Evaluated Data
Angle(c,H) is the angle between the directions of the c-axis and the applied magnetic field. Angle(c,H) = 0° means that the field is applied in a direction parallel to the c-axis. For angle(c,H) = 90°, the field is perpendicular to the c-axis.
Digitized data were obtained from Figure 1 of the paper.
