A novel method of measuring the temperature dependence of the full penetration field, Hp, of polycrystalline Y-Ba-Cu-O hollow cylinders (T O = 92 K) is reported. The probe, placed in the centre of the cylinder, is a polycrystalline Y-Ba-Cu-O bar whose critical current or flux flow voltage is measure
Bulk Y-Ho-Ba-Cu-0 and Y-Gd-Ba-Cu-G samples, which were prepared by a "powder melting process" (PMP) method, have been investigated. The results indicate that J, can be improved and the melting temperature may be changed by Ho and Gd substitution. In our samples the field dependence of J. is rather w
