Growth temperature dependent magnetic properties of Fe film on BaTiO3
Source abstract
Abstract
We report on the growth temperature effect on magnetic coercivity (H C) and saturation magnetization (M S) of epitaxial Fe films grown on BaTiO 3 (BTO). A tensile strain is observed in Fe films grown on tetragonal BTO below the growth temperature of 120 °C, whereas a compressive strain is induced in Fe films grown on cubic BTO above the growth temperature of 120 °C. Combining the lattice mismatch compressive strain and tensile thermal strain, the strongest tensile strain in Fe30 and the compressive strain in Fe400 are opposite trend to the expectation, which may be due to the FeO x interface layer with larger lattice constant. The H C grew from 14.6 to 66.6 Oe as the growth temperature increased from 30 to 400 °C, while the M S reduced from 2129 to 1244 emu/cm 3.
