用单晶法研究了Tl-Sr-Ca-Cu-O系统中Tl-（1223）相的磁化强度和晶内临界电流密度。在77 K和1 T下，由磁化强度推导出的晶内Jc为2-8×104 A/cm ~ 2。在77 K时，H//c轴的不可逆性场H* 约为2 T，H//c轴的不可逆性场H * 约为5 T。
The magnetization and intra-grain critical current density of Tl-(1223) phase of Tl-Sr-Ca-Cu-O system were investigated using single crystals. The intragrain Jc deduced from the magnetization was found to be 2-8×104 A/cm2 at 77 K and 1 T. The irreversibility field H* was estimated to be ∼2 T for H//c-axis and >5 T for H⊥c-axis at 77 K.
