Origin of giant dielectric constant and magnetodielectric study in Ba(Fe0.5Nb0.5)O3 nanoceramics

•High dielectric constant (∼33,000) with low loss (∼0.45) was found at room temperature.•Cole–Cole plot analysis confirmed the formation of barrier layers on grain–grain boundary interfaces.•XANES study confirms the mixed valence state of Fe ion.•Reporting first time about presence of magnetocapacit...
