摘要
This paper analyzes the influence of the deposition conditions (substrate temperature and oxygen flow) on the magnetic moment of Fe304 films grown by reactive RF sputtering. With conversion electron Mossbauer spectroscopy and transmission electron microscopy of specific microstructures we have identified different mechanisms which can contribute to the decrease of M in our samples: decrease of average grain size (superparamagnetism) and distortion of the lattice which may induce mispopulation of tetrahedral and octahedral sites and decrease of crystalline quality. © 1990, Materials Research Society.
