We explore the role of oxygen vacancies in the oxygen evolution reaction (OER) for double
perovskite PrBaCo2O6− δ. Interestingly, we find that largely increasing oxygen vacancies …

Hydrogen-associated electron-doping Mottronics for d-band correlated oxides (eg, VO2)
opens up a new paradigm to regulate the electronic functionality via directly manipulating …

The thermodynamics of defect formation in layered perovskite-like cobaltites RBaCo 2 O 6-δ
(R= La, Nd, Pr, Sm, Gd, Eu, Ho and Y) was investigated via two distinct methods–(I) …

Double-perovskite GdBaCo2O5. 5 (GBCO) exhibits various fascinating features, including
temperature-and magnetic-field-induced ferromagnetic to antiferromagnetic phase transition …

Investigation of ultrafast dynamic behaviors can provide novel insights about the coupling
mechanisms among multiple degrees of freedom in condensed matters, such as lattice …

Materials that show negative thermal expansion (NTE) have significant industrial merit
because they can be used to fabricate composites whose dimensions remain invariant upon …

The ability of cobalt to take, depending on the temperature, pressure, and doping, various
charge and spin states in oxide compounds periodically becomes the topic of scientific …

The paradigm that chemical synthesis reduces the sintering temperature as compared to
solid state synthesis seems to be violated in the case of the PrBaCo2O6− δ double …

The layered EuBaCo 2 O 5+ δ (δ= 0.47)(EBCO) cobaltite shows various magnetic phases at
high temperature and magnetic glassy state at low temperature. Further, the various …

Co L X-ray absorption spectra were used to determine the charge and spin states of ions in
LnBaCo2O5+ δ cobaltites (Ln= Tb, Eu and Gd,). It is shown that with a decrease in the …
