Dzyaloshinskii-Moriya Interaction in Iron Garnets: from crystalline growth to chiral structures and spin-waves

The goal of this postdoc project is to probe and ultimately control how chiral interactions can be induced in rare-earth ion garnet (RIG) thin films. First, the postdoc will be in charge of optimizing the crystalline growth of RIG thin films. The different samples will be characterized in details by X-ray diffraction and magnetometry. In addition, the dynamic magnetic properties of thin films will be probed by ferromagnetic resonance. Secondly, by combining the RIG oxide with a heavy metal overlayer with a strong spin-orbit coupling, magneto-transport analyses will be performed. Finally, specific signatures in the spin-wave spectrum of RIG microstructures, related to the presence of DMI, will be probed.
