Materials and Properties

Y:123; [Y-Ba-Cu-O]
Material Specification for Y:123; [Y-Ba-Cu-O] Process: Flux Growth
Notes: "We focus here on the magnetization of a single crystal (3 x 3 x 0.8 mm3) for a field applied along the c-axis. The single crystal... has been prepared by a flux method... However, due to the poor quality of starting materials a small amount of Sr impurities is present."
Formula: YBa2Cu3O7
Informal Name: Y:123
Chemical Family: Y-Ba-Cu-O
Chemical Class: Oxide
Structure Type:
Manufacturer: In House

Critical Temperature for Y:123; [Y-Ba-Cu-O]
Critical Temperature (K)
89
Measurement Method: Magnetization measurements
"The magnetization has been measured at constant temperatures, in a steady field (Bitter coil) which varied by steps of 0.2 T up to 4 T and 0.4 T or 0.5 T between 4 T and 20 T... The critical current density can be deduced from... the Bean model."
