摘要：

Powder of approximate composition Tl0.6V0.5Sr2Ca2Cu3O(x) was synthesized in O2 at 970-degrees-C from a mixture of oxides of nominal composition Tl2V0.5Sr2Ca2Cu3O(x). The onset T(c) was 110 K. Magnetic hysteresis measurements indicated that above almost-equal-to 60 K the irreversibility behavior was superior to that of TlBa2Ca2Cu3O(x), which has a T(c) of almost-equal-to 118 K. The individual grains were up to almost-equal-to 50 mum in length, with aspect ratios < 10, which may during fabrication promote texturing by mechanical means.
