The chemical preparation of a tin-doped spinel ferrite via the co-precipitation method rendered a sample containing 48.2mass% Fe 3+ , 11.8mass% Fe 2+ and 13.0mass% Sn. Powder X-ray diffractometry data collected with synchrotron radiation source revealed the co-existence of two crystallographic phases: one with cubic (spatial group, Fd3m) spinel and other with trigonal–hexagonal (R3¯c)...
