The results of study of the electron transport properties of La0.7Ba0.3MnO3 (LBMO) strained manganite epitaxial thin films are presented. The films with thickness of 40–100 nm were made using laser ablation at a temperature of T = 700–800 ° C in an at-mosphere of pure oxygen of 0.3–1 mBar. To create a strain, we used ferroelectric sub-strates (011) 0.79PbMg1/3Nb2/3O3-0.21PbTiO3 (PMN-PT) with Curie temperature of 150 C and with high piezoelectric constants. By applying voltage to the PMN-PT substrate, the effect of the ferroelectric polarization and the piezoelectric stress on the electric parameters of the LBMO films was investigated.

ABSTRACTWe examined the influence of momentary annealing on the nanoscale surface morphology of NiO(111) epitaxial thin films deposited on atomically stepped sapphire (0001) substrates at room temperature in O2 at 1.3 × 10−3 and 1.3 × 10−6 Pa using a pulsed laser deposition (PLD) technique. The NiO films have atomically flat surfaces (RMS roughness: approximately 0.1–0.2 nm) reflecting the step-and-terrace structures of the substrates, regardless of the O2 deposition pressure. After rapid thermal annealing (RTA) of the NiO(111) epitaxial film deposited at 1.3 × 10−3 Pa O2, a periodic straight nanogroove array related to the atomic steps of the substrate was formed on the film surface for 60 s. In contrast, the fabrication of a transient state in the nanogroove array formation was achieved with RTA of less than 1 s. However, when the O2 atmosphere during PLD was 1.3 × 10−6 Pa, random crystal growth was observed and resulted in a disordered rough surface nanostructure after RTA.
