We present a comprehensive study of the magnetic properties for La doped Bi2FeMnO6 (LBFM) ceramic and film which was first deposited on (100) SrTiO3 substrate by pulsed laser deposition method. The LBFM film is antiferromagnetic or weak ferrimagnetic at room temperature and it shows clear magnetic anisotropy. But it is not sure whether the spin-glass behavior is present in LBFM film because of the influence from substrate. Compared to the film, LBFM ceramic shows different magnetic properties. It has a lower TN and all the observations indicate that LBFM ceramic shows spin-glass behavior.

A ferroelectric thin film of Aurivillius phase K0.5Bi4.5Ti4O15 (KBT) with a complex bismuth layer-structure was fabricated using the pulsed laser deposition method. The thin film grown on Pt/Ti/SiO2/ Si substrate shows a strong c-axis orientation, as revealed by x-ray diffraction results, and platelike growth of grains. A Pt/KBT/Pt capacitor shows a maximum polarization of about 20 µC/cm2. In addition, the capacitor also shows good fatigue resistance, with a decrease of 14.5% in the remanent polarization after 107 switching cycles. This Aurivillius phase with four layers of TiO6 …

Low energy metal ion implantation has been used to combine an easy “bottom-up” way of creating and tuning different topographic structures on submicron to micrometer scales with the embedding of a metallic element-rich functionalized layer at the surface for a variety of scientific and technological applications. The self-organizing and complex patterns of functionalized topographic structures are highly dependent on the implanted metal ion species, variations in the geometric confinement of the buckled areas on the larger unmodified elastomer film, and the boundary conditions of the buckled regions. Systematic investigations of these dependencies have been carried out via optical and atomic …
