Microstructural Analysis of Garnet-Heavy Metal Heterostructures
… materials on Si requires further microstructure analysis. Polycrystalline dyprosium iron garnet (DyIG) has been successfully grown on Si with PMA due to an external rapid thermal anneal after pulsed laser deposition [8]. However, crystallization is limited to thicknesses above 20 nm. Furthermore, …
