【摘要】 本文报导用激光基座法(LHPG)生长的二种Bi2-xPb×Sr2Ca2Cu4Oy(x=0.3和0.5)超导纤维。其转变温度Tc分别为80和107K。实验还表明Tc温度与纤维的控制次数、退火工艺等因素有关。更多还原

【Abstract】 We report here two superconductor fibers grown by LHPG method and with the normal constitutions Bi2-xPbxSr2Ca2Cu4Oy (x = 0.3 and 0.5). The onset temperatures for thes fibers are 80 K and 107 K respectively. It has also been shown that the onset temperature Tc has relation to the times of regrowth, annealing conditions and so on.更多还原
