The Discovery of Manganites and the Colossal Magnetoresistance Effect

Abstract

It is widely recognized that the first paper reporting results for manganites was presented in 1950 by Jonker and Van Santen [2.1]. In that first publication, La was replaced either by Ca, Sr, or Ba, and results for polycrystalline samples of (La,Ca)MnO3, (La,Sr)MnO3, and (La,Ba)MnO3 were reported. The main result was the appearance of ferromagnetism in these compounds, as described below. Jonker and Van Santen clarified in their first publication that the term “manganites” is not rigorous, and only compounds containing tetravalent Mn should actually be called manganites. However, they write “For the sake of simplicity the compounds containing trivalent, as well as those containing tetravalent, manganese will be designated as manganites”, a convention that it is still followed today.
