X-ray diffraction patterns (red circles) along with the fits (black lines) for PrBaCo2O6. The residues are shown as blue lines at the bottom and the Bragg peaks are shown as green bars. Inset shows the ordered double perovskite structure projected along the b-axis.
Electron diffraction patterns of PrBaCo2O6 along main zone axis. Note the presence of twinning structure in the  ED pattern.
(a) and (b) HRTEM images of PrBaCo2O6 along the  and  zone axis. (c) (100) HRTEM image of twinning area and corresponding structural model. The calculated images for  (defocus value Δf = −45 nm, t = 6 nm) and  (defocus value Δf = −55 nm, t = 7.5 nm) are given as inset.
MZFC(T) (open symbols) and MFC(T) (closed symbols) curves of PrBaCo2O5+δ: (a) δ = 0.80, (b) δ = 0.93, (c) δ = 0.95, and (d) δ = 1.00, recorded under a magnetic field of 0.3 T.
M vs H curves of PrBaCo2O5+δ: (a) δ = 0.80, (b) δ = 0.93, (c) δ = 0.95, and (d) δ = 1.00, recorded at 5 K.
