Notes: The authors cite J.Z. Liu et al., Phys. Lett., Vol. 121, 305 (1987), and summarize the procedure as follows. "The iron-doped Y-Ba-Cu-O single crystals were grown by the modified self-flux technique... The rectangular slab-shape samples used in the experiment have varied dimensions, typically 0.8 x 0.6 x 0.04 mm3."

Measurement Method: SQUID magnetometer
"... the magnetic hysteresis loops are taken in a commercial SQUID magnetometer in the field range of (-5.5 T to 5.5 T) over a wide temperature range. The magnetic field is operated in the persistent mode and is oriented along the c axis of the single crystal. The magnetization data are obtained about 1 min after the field reaches stability... The critical current densities (Jc) of single crystals are deduced from measurements of the magnetic hysteresis curve."
