Combinatorial sputtering synthesis of TbCu7-type Sm-Fe based compounds: a study on phase, composition, and extrinsic magnetic properties.
We investigated the effect of composition on the phase and extrinsic magnetic properties of TbCu7-type SmFe-based compounds using combinatorial sputtering technique. Composition-spread thin films of SmFex (x=6.4 to 12.7) and SmFexN (x=6.8 to 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 SmFe9.8 and SmFe9.5N and beyond this composition, the α-Fe secondary ferromagnetic phase emerges. The coercive field and remanence of the SmFe9.5N is estimated to be ~0.8 T and ~1.2 T respectively. Further, scanning transmission electron microscopy (STEM) was performed at SmFe9.5N 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 TbCu7-type SmFe-based compounds, which can be utilized to tailor magnetic properties for targeted advanced magnet applications.
