| Abstract(in English) | The magnetoelectric Cr_2O_3 films are deposited on r- and c-cut sapphire substrates at a substrate temperature higher than 580℃. Increasing the r-cut substrate temperature, the depth of the trenches between grains becomes deeper, leading to rough surface. However, the crystallinity is improved due to higher migration energy. The surface of one grain is step-terrace structure. In the meantime, the c-oriented films surface is flat regardless of substrate temperature more than 600℃. The value of the surface roughness Ra is approximately one-tenth comparing to that of r-oriented films. The lattice parameter of direction perpendicular to plane is consistent of bulk value. The stress originated from the mismatch between film and substrate is completely released. From the results of the reciprocal space mapping (RSM), the c-oriented films grow with twin, while the r-oriented films grow without twin. Pt/Co/Pt/r-oriented Cr_2O_3/Al_2O_3 of the magnetic image was measured by Magnetic force microscopy (MFM). There wasn't difference magnetic image before and after field cool. |
