The main goal of our project is the investigation of ultrafast magnetization dynamics in correlated materials under the influence of injected spins via the inverse spin Hall effect. For an effective spin injection, we need samples with a high SOC material in contact with the respective correlated material.
On our poster, we report on the fabrication of corresponding LSMO|Pt bilayer systems. We have tested a multitude of preparation techniques, namely metalorganic aerosol deposition, xenon ion sputtering and thermal vaporization, and compare our fabricated samples with respect to quality of epitaxial growth, interface quality and to the magnetic properties of the LSMO.
We acknowledge financial support by the DFG within the SFB 1073 - Atomic scale control of energy conversion.
