he temperature dependence of the inductance of samples contain TiO2, measured in 150 mT magnetic field (ZFC), is shown in Fig. 5. In the zero-field- cooled (ZFC) procedure, the selected magnetic field was applied to samples when the temperature of samples reached below Tc. The Tc of TiO2-free sample was found to be 90K in the field of 150mT.The value of Tc was reduced to the lower temperatures with an increase in the TiO2 content. The lowest Tc value (82 K) in 150-mT magnetic field was obtained for sample containing 7 wt.% of TiO2.
