The compacted powders were located on a crucible with Y2O3 powder freely poured and a buffer layer of pressed Y2O3 to avoid liquid to spread on the furnace plate. The superconducting transition temperature was determined by a standard four-point method at temperatures between 40 and 100K. The transition temperatures of Y1050-1 and Y1050-2 were found to be 91.6 and 92.9K at zero magnetic fields, respectively. The magnetization measurements were performed using a vibrating sample magnetometer (VSM) on the same system at 5, 40, and 77K. The critical current densities for Y1050-1 and Y1050-2 samples were determined to be 6.5×103 and 5.6×103A/cm2 at 77K in zero magnetic fields, respectively. The trapped magnetic field measurements of the samples were performed by using a Hall probe scanning device and a Fe-Nd-B permanent magnet at 77K. It was found that the trapped magnetic field of the Y1050-1 sample is higher than that of the Y1050-2 sample.
