Abstract

The oxidation of thin films of gadolinium, iron and Gd3Fe5 has been investigated by transmission electron microscopy and diffraction between 300 and 1200‡ C. The oxidation products for gadolinium and iron films are consistent with the oxidation mechanism proposed for bulk material. Thin films of Gd3Fe5 do not oxidize completely to give gadolinium iron garnet, high densities of garnet and orthoferrite inclusions are observed. An unusual form of grain growth is also observed in these films.
