In this preliminary report, we present the impedance characteristics of poly-crystalline europium manganite, a promising colossal magneto resistance (CMR) system investigated under optical (∼5 eV) and magnetic (0.1 T) perturbations yielding some clues on the charge build-up and dispersion processes. This may possibly be resulting from switching between ferromagnetic and anti-ferromagnetic phases through a charge transfer transition mediated process centering Mn3+/4+ 3d spins thereby meriting a more detailed study correlating with magnetic measurements.
► In this study, using opto-, magneto-opto impedance techniques, experimental proof for charge growth in europium manganite (EuMnO3) near the region of its Neel temperature is presented. ► This study gives data related to dielectric properties of europium manganite. ► This study may open-up new avenues for investigating the dielectric characteristics of many electronic-ceramics.
