“…2(b)], we observed Bragg peaks at 2θ = 28.18°, 34.06°, 39.82°, and 44.67°corresponding to (011), ( 110), (111), and (021) planes of antiferromagnetic FeSn phase (shown as green dashed lines) and Bragg peaks at 2θ = 30.05°, 40.83°, and 43.05°correspond to (015), ( 002) and (024) planes of the ferromagnetic Fe 3 Sn 2 phase (shown as red dashed lines). 44,53 Therefore, Ta seed layer Fe 3 Sn 2 has both ferromagnetic (Fe 3 Sn 2 ) as well as antiferromagnetic (FeSn) phases.…”
