| Abstract(in English) | We have fabricated YBCO bicrystal Junction SQUIDs having various inductance values and studied the characteristics of flux- modulation voltatage.Generally,the modulation voltage of high Tc SQUIDs were lower than IcRn value.From the comparison of experimental value and theoretical value,it is found that the thermal noise rounding of the I-V characteristic plays a major role in reducing the modulation voltage in the range of the noise parameter of γ=Icφ_0, πk_BT20.On the other hand,another effect of the noise flux in the SQUID loop generated by noise currents contribute to reduce the modulation voltage in the Lange of γ>20.W e have also studied the relation between the normal resistance of the grain boundary junction and the modulation voltage of the SQUIDS. |
