Abstract
The authors have not observed any normal electron spin resonance (ESR) signal over a temperature range of 95-300 K in high-Tc BiPbSrCaCuO superconductors with trace dopant (1*10-3 g/g) of Ti, V, Cr, Mn or Mo. Strong zero-field microwave absorptions are observed in all Bi-based compounds below 108 K. Especially, two overlap microwave absorptions are observed in BiPbSrCaCuO doped with Cr and they contract at H=0 as the temperature increases.
