摘要: 应用流体静压法制备YBaCuO体系大型高Tc超导棒材。样品尺寸为11 mm115 mm,其中外形规正,密度均匀。超导转变参数为:起始转变温度为105~106 K,零电阻温度为89~92 K,中点转变温度为92~93 K,转变宽度为5 K左右。Abstract: Using the hydrostatic pressure method we have prepared some uniform superconducting YBaCuO bars with regular shape of 11 mm diameter and 110 mm length. The samples show onset of superconductivity at 105~106 K. Zero resistance in the range from 89 K to 92 K, and resistive transition width 5~8 K.
