Magnetic ordering in sol-gel-based Tm3Fe5O12 thin film

In the quest to utilize rare-earth garnets (ReIG) with perpendicular magnetic anisotropy (PMA) in futuristic spintronics, the attention turned towards iron garnet thin films. Among this family, the one candidate is Tm3Fe5O12 (TmIG) that manifests PMA with excellent Gilbert damping, making this material a potential candidate in magnonics devices. Here, we report a cost-effective deposition approach of the TmIG thin films deposited on a thermally oxidized Si(100) substrate. The homogeneous TmIG (approximate to 22 nm) thin film shows a roughness of approximate to 1.5 nm. The magnetic properties of thin films indicating the compensation temperature 15 K. Experimental findings present a method for the deposition of TmIG thin films, which is a potential candidate for fabricating futuristic compact devices.
