摘　　要：用高ＴｃＴｌＢａＣｕＯ超导薄膜制作成功了双孔ＲＦ－ＳＱＵＩＤ。在液氮温度测试三角波的峰一峰值为１０μＶ，信噪比明显优于ＹＢａＣｕＯ薄膜器件。在没有磁屏蔽的情况下，磁通分辨率优于。A doublehole RF-SQUID from TIBaCaCuO superconducting thin film was fabricated. The triangular patterns in response to. the flux applied is about 10 μV peak to peak at 78K and the signal to noise ratio is superior to that of the device from YBaCuO thin film. The flux resolution is better thais 5 ×10-3φ0 in the care without magnetic shield.
