The temperature dependence of inductance for Y123 containing 5 wt.% TiO2 (prepared by FQMG) in various magnetic fields in the ZFC regimes is shown in Fig. 6. The inductance transition indicates a regular broadening with increasing magnetic field up to 580 mT, showing that the sample is of low quality with weak-link characteristics. In the FC regimes, the same sample showed more broadening of inductance with increasing magnetic field.
