The study investigated the phase stability, ferroelectricity, and magnetism of highly crystalline epitaxial epsilon-Fe2O3 films deposited on SrTiO3(111) substrates. The results showed the appearance of a secondary phase after annealing, and a clear saturated and opened polarization-electric field hysteresis loop at room temperature, as well as a magnetic phase transition at 155 K.
The phase stability, ferroelectricity, and magnetism of highly crystalline epitaxial epsilon-Fe2O3 films deposited on SrTiO3(111) substrates are reported. Temperature-dependent x-ray diffraction measurements revealed that alpha-Fe2O3 appeared as a secondary phase after samples were annealed up to 1000 & DEG;C. A clear saturated and opened polarization-electric field hysteresis loop with the remnant polarization & SIM;2.6 mu C cm(-2) and coercive electric field & SIM;100 kV cm(-1) was obtained at room temperature using a conventional ferroelectric measurement technique. The magnetic phase transition was observed at 155 K. Magnetization-magnetic field measurements revealed that magnetic softening via the phase transition accompanied a reduction in the coercive field from 10 to 6.8 kOe, which is smaller than the coercive field reduction previously observed for epsilon-Fe2O3 nanoparticles.
