We study the effects of a partial substitution of Ba with the smaller cation Ca in the layered cobaltites YBa Co2 O5+δ for δ≈0.5. Neutron thermodiffractograms are reported for the compounds Y Ba0.95 Ca0.05 Co2 O5.5 (xCa =0.05) and Y Ba0.90 Ca0.10

In this work we study the physical properties of the layered cobaltites YBaCo2 O5.5, focussing on the role of cationic disorder and size effects by a partial substitution of Ba by Ca. We have synthesized the polycrystalline compounds Y (Ba1 - x Cax)

We have synthesized the layered cobaltites YBaCo2 O5 + δ with different oxygen contents (δ1 and δ2), and characterized its structural and physical properties using various experimental techniques within the 80-500 K temperature range. Two superstr
