MnFeCo4Si2 R-3m CIF (Kitagawa 2026, paper-derived)
.cifPaper-derived CIF of the GNoME-discovered soft ferromagnet MnFeCo4Si2 (Materials Project mp-3203253), built from the Rietveld refinement of Kitagawa & Naganuma, "Experimental investigation of magnetic properties of MnFeCo4Si2 discovered by GNoME" (arXiv:2603.22748, 2026). Hexagonal setting of R-3m (No. 166): a = 3.9978 Å, c = 19.583 Å; Mn 3b, Fe 3a, Si 6c (z=0.24831), Co1 6c (z=0.37328), Co2 6c (z=0.12334). Validated: R-3m at symprec 0.01/0.1, 24 sites, Z=3, min pair distance 2.42 Å, density 7.40 g/cm3. Measured properties (source paper): soft FM, Tc = 1039 K, Ms = 161.35 emu/g (11.63 μB/f.u.) at 50 K, Hc = 3.7 Oe.
