Abstract
A comparable study of the microstructure and magnetic properties was performed for magnetite
films deposited on (100)-oriented MgO and SrTiO3 (STO) substrates. The growth of strained high
quality Fe3O4 films was confirmed by x-ray diffraction analysis and Raman spectroscopy
measurements. The surface morphology and magnetic properties of the two films were found to be
obviously different. Moreover, a stripelike magnetic domain structure was observed in the film on
STO. Substrate-induced strain is believed to be responsible for these observations, which
significantly affects the magnetic anisotropy and the magnetic coupling at the antiphase boundaries
in the films. © 2008 American Institute of Physics.
