ThMn12-ordered SmFe12 has been considered one of the most promising candidates as a competitive alternative to state-of-the-art permanent magnets. In this study, SmFe12/Fe (001) composite thin films with high extrinsic coercivity were successfully demonstrated. The films were grown using molecular beam epitaxy (MBE), with systematic variation of Sm and Fe flux ratios to optimize their magnetic and structural properties for high-performance applications. For Sm-rich films, a c-axis textured SmFe12 structure with in-plane magnetization was achieved. An exceptionally high coercivity of 0.44 T was observed at an Fe/Sm ratio of 6, attributed to the formation of intergranular phases that enhance magnetic stability.The growth of SmFe12 thin films on MgO (100) using MBE was investigated, with the experimental setup including an MBE schematic, RHEED patterns, and XRD profiles highlighting the temperature dependence, as shown in the following schematic figure.
