In-situ X ray characterization of Multiferroics oxide thin Films during Pulsed Laser Deposition at the Nano Beamline of the National Synchrotron Facility ANKA

Multiferroics are attracting increasing interest, the coexistence and coupling of ferroelectric and magnetic orders has made them as potential candidate for novel multifunctional devices such as sensors, transducers, memories and spintronics. Multiferroic magnetoelectric (ME) composite systems, such as ferromagnetic–ferroelectric heterostructures offer a novel route for integrating ferroelectric and ferromagnetism. The PhD shall perform growth studies of Multiferroic magnetoelectric (ME) composite systems with the new PLD chamber with the unique feature, that it can be integrated into the NANO beamline at the ANKA synchrotron facility. The candidate shall perform In-situ X-ray characterization during pulsed laser deposition (In-Situ PLD) combined with high pressure RHEED to study the time evolution of the crystal structures and the microstructure of the oxide thin films, (e.g. the domain size and the distribution of crystalline orientation) at the growth temperature, during the film formation. The main focus will be given to the study of the PLD growth and properties of bilayers of the La2/3Sr1/3MnO3 (LSMO) half-metal combined with BiFeO3 and epitaxial grown onto SrTiO3 (001) and other type of substrates with different type of miscut.

The candidate will perform systematic experimental investigation of the influence of the growth parameters like annealing temperature, gas pressure, pre and post-treatment on the microstructure, strain, the defect density and interface quality of the grown thin films. One goals is to detect the critical thickness of morphology instabilities.
