Abstract Hematite (α‐Fe2O3) thin films are obtained by atomic layer deposition (ALD) in the temperature range 200 − 350°C using ferrocene and ozone as the precursors. A micro‐pulse process facilitates the precursor adsorption and shortens the ferrocene dose time to 5 s. When tested on ...

MgO-supported manganese carbonyl complexes were prepared by chemical vapor deposition of Mn(CO)5CH3 on partially dehydroxylated, high-area MgO powder. X-ray absorption spectra identify the resultant surface species, on average, as Mn(CO)4(Os)2 (where the two oxygen ligands are part of the MgO ...
