Abstract

AC Susceptibility measurements were taken for three doped La_2-xSr_xCuO_4-δ (LSCO) samples with x= 0.14, 0.16, 0.18, fabricated using identical temperature and annealing profiles. Susceptibility data is dominated by its intragranular response, which was confirmed using their corresponding harmonic susceptibilities. SEM reveals that at x=0.14 the material is fused, thereby eliminating intergrain interaction – corresponding to susceptibility that is purely intragranular. At x=0.16 and x=0.18 grain boundaries are present, but not causing significant loss such that the intragranular losses still has greater magnitude.
