Abstract

Variation of non-resonant microwave absorption (NRMA) signal amplitude in single-phase Bi-2212 (5 wt % Ag) sintered pellets (T-c(o) similar to 96 K) while increasing temperature from 15 to 105 K has been investigated and discussed. These studies show an undulatory behavior of an initial fall in the amplitude (15-71.8K) with a subsequent narrow weak temperature independent region (71.8-75.6 K) and then a rise peaking at similar to 82.5 K followed by a final exponential fall (82.5-105 K). A detailed discussion on earlier reported data has suggested that this undulatory behavior cannot be understood in terms of existing approaches involving effect of Josephson interactions (JI) alone among vortices. In our opinion, the entire undulatory behavior observed in the present samples can be explained with the inclusion of electromagnetic interaction (EMI) along with JI.
