| Abstract: | The oxyfluoride garnets of formula Y3Fe5?xMxO12?xFx and Gd3Fe5?xMxO12?xFx (M = 3d transition element) result from partial substitution of O2? by F? in Y3Fe5O12 and Gd3Fe5O12 oxides. The cationic charge compensation is obtained by replacing the Fe3+ ions by divalent ions as Mn2+, Co2+, Ni2+, Cu2+ or Zn2+ ions. The site occupied by some of these ions (Mn2+, Ni2+, Zn2+) is determined by magnetic or Mössbauer measurements. |
