Notes:
We have measured intragrain critical currents in field-oriented samples of a rare-earth-free high-Tc superconductor (Tl0.75Bi0.25)1.33Sr1.33Ca1.33Cu2 O6.67+δ, the "1212'' phase. The critical current Jc is anisotropic. For fields oriented along the conducting planes, a simple scaling of Jc with field is found. The critical current scales to zero at a field HBc2 (T) which is in good agreement with the form predicted by the flux creep theory.
