AbstractFor the flux pinning enhancement of (Sm0.5Y0.5)Ba2Cu3O7−δ superconductors we have developed a fabrication method of zone-melting-growth with CeO2 addition to the calcined (Sm0.5Y0.5)Ba2Cu3O7−δ powder. To analyze the effect of CeO2 addition, a zone-melted sampl...
AbstractFor the flux pinning enhancement of (Sm0.5Y0.5)Ba2Cu3O7−δ superconductors we have developed a fabrication method of zone-melting-growth with CeO2 addition to the calcined (Sm0.5Y0.5)Ba2Cu3O7−δ powder. To analyze the effect of CeO2 addition, a zone-melted sample without CeO2 addition was fabricated using the same process. Microstructure analysis of CeO2 added sample showed that fine ellipsoidal (Sm0.5Y0.5)2BaCuO5 inclusions were uniformly dispersed in a large (Sm0.5Y0.5)Ba2Cu3O7−δ grain. Magnetization hysteresis was measured to analyze flux pinning effect using a SQUID magnetometer. At 10 K and 10 kG the sample with CeO2 addition showed two times larger magnetization hysteresis than the sample without CeO2 addition.
