Abstract: We investigated the effect of composition on the phase and extrinsic magnetic properties of TbCu 7 -type SmFe-based compounds using a combinatorial sputtering technique. Composition-spread thin films of SmFe x (x =6.4–12.7) and SmFe x N (x =6.8–12.8) were synthesized using a linear shutter-assisted combinatorial sputtering technique. A high-throughput composition, phase, and magnetic characterization were performed on 18 different locations along the film using X-ray diffraction (XRD), X-ray fluorescence (XRF), and magneto-optical Kerr effect (MOKE) magnetometry. The optimal composition with the highest fraction of the main phase was found to be in SmFe 9.8 and SmFe 9.5 N and beyond this composition, the α -Fe secondary ferromagnetic phase emerges. The coercive field and remanence of the SmFe 9.5 N are estimated to be ∼0.8 T and ∼1.2 T, respectively. Further, scanning transmission electron microscopy (STEM) was performed at SmFe 9.5 N to correlate the microstructure with their extrinsic magnetic properties. Overall, this study demonstrates the impact of composition variation on the phase and extrinsic magnetic properties of TbCu 7 -type SmFe-based compounds, which can be utilized to tailor magnetic properties for targeted advanced magnet applications. [Display omitted] • Synthesized composition spread thin film using combinatorial sputtering technique. • Performed high-throughput composition, phase, and magnetic characterization methods. • Generated 18 data points for composition, phase, and extrinsic magnetic properties. • Achieved maximum Fe:Sm ratio with single TbCu 7 -type phase in Sm x Fe and SmFe x N.
