The XRD patterns of ribbons spun at a high wheel speed of 40 m/s show that a pure TbCu<sub>7</sub>-type structure is formed only for x=0.1, while a mixture of CoSn appears at the grain biundary for x ≥ 0.2 and 2:17 phase appears for x ≥ 0.4. The Rietvield refinement result shows that Sn prefers to occupy the 2e sites in TbCu<sub>7</sub>-type structure, which is similar to Ge. The coercivity of melt spun SmCo<sub>7-x</sub>Sn<sub>x</sub> ribbons is enhanced from 1.9 kOe for x=0 to 8.4 kOe for x=0.3 . The grain size is reduced with Sn substitution from 100-400 nm for SmCo<sub>7</sub> ribbons to 50-100 nm for SmCo<sub>6.7</sub>Sn<sub>0.3</sub> ribbons, which also contributes the coercivity in addition to the enhancement of magnetic anisotropy field by the occupation of Sn atoms at 2e sites.</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Keywords</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>X-ray diffraction; cobalt alloys; crystal structure; grain size; magnetic materials; melt spinning; permanent magnets; samarium alloys; tin alloys; Rietvield refinement; SmCo<sub>7-x</sub>Sn<sub>x</sub>; XRD patterns; coercivity; crystal structure; grain boundary; grain size; high wheel speed; magnetic anisotropy field; magnetic properties; melt spun SmCo<sub>7-x</sub>Sn<sub>x</sub> ribbons; size 100 nm to 400 nm; size 50 nm to 100 nm; Coercive force; Crystals; Magnetic anisotropy; Magnetic properties; Tin; X-ray scattering; <formula formulatype=${rm TbCu}_{7}$; Crystal structure; melt spinning; permanent magnet;
