Manganese‐Doped Zirconia Nanocrystals

European Journal of Inorganic Chemistry, 2008
AbstractIn recent theoretical work, it was predicted that transition‐metal‐doped zirconia (ZrO2) can be ferromagnetic at room temperature with a dependence on the metal dopant and its oxidation state and concentration. For experimental verification of these predictions, manganese‐doped ZrO2 nanoparticles were synthesized.

The Systems Zirconia‐Lanthana and Zirconia‐Neodymia

Journal of the American Ceramic Society, 1955
The minimum amounts of lanthana and neodymia required to stabilize zirconia into a cubic form are 30 and 20 mole %, respectively, at 980°C. X‐ray diffraction studies have established the upper limit of the two cubic solid solution regions as approximately 40 mole %.
