Abstract:In this study, we thoroughly examined the impact of heat treatments and hole count (p) on the properties of LnSrBaCu 3 O 6+z (Ln = Eu, Sm, Nd) compounds. We focused on preparation, X-ray diffraction with Rietveld refinement, AC susceptibility, DC resistivity measurements, and heat treatment effects. Two heat treatment types were applied: oxygen annealing [O] and argon annealing followed by oxygen annealing [AO]. As the rare earth Ln's ionic radius increased, certain parameters notably changed. Specifically, c… Show more
