| 摘 要： | 本文报导用Ｔｌ２Ｂａ２ＣａＣｕ２Ｏ８外延超导薄膜在ＬａＡｌＯ３衬底上研制的台阶结及其特性，在液氮温度下，当台阶结受到９．２０ＧＨｚ的微波辐照时，从Ｉ－Ｖ曲线上可以观察到第九级夏皮诺微波感应台阶。在液氮温度下，台阶结的临界电流随外磁场的变化较好地附合夫琅和费衍射关系。

| Abstract: | The preparation of Tl2Ba2CaCu2O8 step edge junctions on LaAlO3 substrates and thire characteristic are reported. At liquid nitrogen temperature, the 9th Shapiro steps can be seen on the I-V curves under 9. 20 GHz microwave radiation. The dependence of the critical current of the step edge junction on the applied magnetic field accords with Fraunhofer diffraction quit well at liquid nitrogen temperature. |
