In this work, single crystals with a BaFe12 − (x + y)SnxCoyO19, 0 ≤ x ≤ 2, 0 ≤ y ≤ 2 composition, were grown by slow cooling and the TSSG technique, using a mixture of 0.4Na2O–0.6B2O3 as solvent. Taking into account previous results about primary crystallization regions, saturation temperatures, physical properties of the solutions, digital simulations and several previous growth experiments, suitable growth conditions were proposed and used. Crystals grown under these conditions were characterized from the point of view of their perfection and compositional homogeneity. Magnetic properties were also investigated and their evolution as a function of the level of substitution stated.
