Analytical electron microscopy (AEM) was performed with a AEM equipped with a field emission gun, an electron energy-loss spectrometer, and an energy-dispersive x-ray spectrometer. The microstructure consists of alternating lamellae of CoO and Ca- stabilized cubic-ZrO[sub 2], each up to 1[mu]m wide, and a thin (100- 200 nm) irregular layer of Co[sub 3]O[sub 4] spinel extending into the CoO from the flat ZrO[sub 2] interface.
