Distribution of Relaxation Times analysis of evolution of Oxygen Reduction Pathways for ionic conductor infiltration on MIEC cathode
Rakhi Saha, Preethi Sudarsan, Manju Kumari +4
Solid oxide fuel cells (SOFCs) are promising electrochemical energy conversion devices; however, the sluggish cathodic oxygen reduction reaction (ORR) remains a major limitation fo…
Hexagonal polymorphism induced structural disorder and dielectric anomalies of Ca/Mn modified BaTiO3
P. Maneesha, Dilip Sasmal, Rakhi Saha +7
This work involves the local structural investigation of the samples using Extended X-ray Absorption Spectra (EXAFS) analysis to investigate structural changes due to the Ca and Mn…
Room temperature Multiferroicity and Magnetoelectric coupling in Ca/Mn modified BaTiO3
P. Maneesha, Koyal Suman Samantaray, Rakhi Saha +7
Materials with magnetoelectric coupling (MEC) between ferroic orders at room temperature are emerging field in modern technology and physics. BaTiO3 is a robust ferroelectric in wh…
Room temperature ferromagnetism induced by high valence cation V/V substitution in SrFeO
Rakhi Saha, Koyal Suman Samantaray, P Maneesha +7
The structural and magnetic effects of non-magnetic vanadium (V) doping in helimagnetic SrFeO (SFO) are investigated, focusing on up to 3% substitution at the Fe site. Str…
