Field dependence of the super-current density in NEG-123 samples with the same content of Gd-211 , , but various contents of . All the samples were measured at with axis. The current density increased in the whole field range up to the content of and decreased thereafter. Note the relatively high critical current density of at self-field and , which was achieved with . Inset: The curves of the sample with under liquid nitrogen pumping , at liquid nitrogen , at liquid argon , and at liquid oxygen ( axis). Note the very high critical current density of at self-field and at .
