High--$T_c$ RF SQUIDs with Large Inductance of Quantization Loop

, 2003
Experimental data on signal and noise characteristics of high--$T_c$ RF SQUIDs with large inductance of quantization loop are presented. The SQUIDs were produced by a thick--film HTS--technique of painting on the Y$_2$BaCuO$_5$ substrate.
