Figure S3. Crystal structure (cubic, Ia3d) of garnet calculated using the crystallographic data in reference 1 Holmium iron garnet (HoIG) is a member of the isostructural garnet family and ferrimagnetic oxides. The general formula for a garnet is C3A2D3O12 where the C cations occupy dodecahedral sites, the A cations occupy octahedral sites, and the D cations occupy tetrahedral sites in the crystal structure as shown in Figure S3. In the case of HoIG; (Ho3)C{Fe2}D[Fe3]AO12, 24Ho3+ occupies dodecahedral sites and 16Fe3+ occupies octahedral sites and 24Fe3+ occupies tetrahedral sites.2
