英文摘要 | The characteristics of high-Tc step-edge or bicrystal junctions and SQUIDs are examined. The IcRn product of junctions was found to be proportional to (jc)p with p ~ 0:5 over several orders of magnitude in jc and at various temperatures. The V-Ф and noise characteristics of SQUID were compared with the numerical expression of Enpuku et al. We demonstrate that 1=f noise can be induced with an applied external magnetic field. The microwave radiation reduces the modulation depth, Vpp, distorts the V-Ф curve, and decreases the field sensitivity of SQUID magnetometers. |
