The observed variations of lattice parameter and cell volume with Ca content are shown in Fig. 3. It is well known that Ca substitution at the R-site decreases the oxygen content of R-123 compounds; however, La substitution at the Ba-site increases the oxygen	./cache/work_zpnbhjwhkbc53kiy2abyiq2spu.pdf	./txt/work_zpnbhjwhkbc53kiy2abyiq2spu.txt
