Polycrystalline samples of (ZrO2)0.8(Y2O3)0.2 ceramic oxides doped with vanadium, iron, nickel, and cobalt are synthesized and characterized using X‐ray diffraction, scanning electron microscopy, and electron paramagnetic resonance techniques. It is observed from EPR studies that the nickel‐doped sample exhibits a rather broad signal comprising a large number of narrow lines. It is noted from the XRD and SEM studies that all the samples consist of mainly two phases, monoclinic and tetragonal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
