Summary

SAMPLES WERE PREPARED BY A SOLID-STATE REACTION AND CHARACTERIZED BY ENERGY-DISPERSIVE X-RAY MICROANALYSIS, RESISTIVITY MEASUREMENTS, AND MAGNETICALLY MODULATED MICROWAVE ABSORPTION (MAMMA). LONGER ANNEALING TIMES RESULTED IN MORE HOMOGENEOUS SAMPLES HAVING A SINGLE SUPERCONDUCTING TRANSITION TO ZERO RESISTANCE AT 108 AND 105 K AT 0.1 AND 1 MILLIAMPERE, RESPECTIVELY. THE MAMMA MEASUREMENTS CLEARLY SHOW DIFFERENCES IN SAMPLE HOMOGENEITY WITH DIFFERENT ANNEALING TIMES.
