Materials and Properties

Tl:1223; [Tl-Ba-Ca-Cu-O]
Material Specification for Tl:1223; [Tl-Ba-Ca-Cu-O] Process: Melt Processed
Notes: The authors cite A. Maignan et al., Physica C, Vol. 219, 407 (1994), and summarize the procedure as follows. "Single crystals have been grown from melts of BaCuO2:CaO:Tl2O3 in the ratio 2:2:1/2. ... One of these crystals, with dimensions 0.81 x 0.48 x 0.13 mm3, was retained for the magnetic study."

Critical Temperature for Tl:1223; [Tl-Ba-Ca-Cu-O]
Critical Temperature (K)
114
Measurement Method: SQUID magnetometer
"...Jc values and the irreversibility line location derived from magnetic hysteresis loops are presented... The magnetic measurements were carried out by means of a 5.5 T SQUID magnetometer in the configuration H//c. ... The critical current densities have been evaluated from the hysteresis loops using an extended Bean model for rectangular shaped samples. ... For temperatures not too close to Tc ( ≤ 105 K), the determination of H (T) using the closing points of the hysteresis loops is quite definite."
