Abstract

Transmission Electron Microscopy (TEM) was used to analyze the interface between RF sputtered alumina thin films and (NiZn)Fe2O4 substrates. Bright field and dark field TEM images, High Resolution Electron Microscopy (HREM), and Selected Area Electron Diffraction (SAED) patterns provided direct evidence of eta-alumina crystalline regions near the filmsubstrate interface. The orientation and existence of the crystalline alumina phase was dependent on the substrate crystal orientation.
