| Abstract(in English) | LFO and CFO films are deposited by PLD method. Targets are calcined using powder prepared by traditional solid solution (SS) and Pechini method. The targets surface is quite smooth after ablation in both LFO and CFO cases, probably due to the homogeneous distribution of each atom in the target. Density of the target by Pechini is 95.5% and 96.4% for LFO and CFO. The surface of the CFO film using Pechini target shows step-terraces structure. Thickness difference between deposited film and estimated thickness from the periodicity of RHEED oscillation around the initial growth region is -48% and +6.3% using SS target and Pechini target, respectively. It reveals that the precise control of deposition rate is achived using Pechini target. The volume calculated from the XRD results of LFO thin film is correspondence with that of bulk within 0.4%. In the case of CFO thin film, the unit volume is of CFO2.5. The required growth period is doubled after 5 units growth comparing to that before 3 units growth. The probability of growth of the grain with 0.7 nm in height increased from 18% to 34% before and after 3/5 units growth. It is expected that the CFO2.5 grew with the doubled lattice constant along the normal direction of the surface. Highly dense target prepared by Pechini method is promising target to obtain high quality thin films. |
