Description
Moessbauer study of synthesized ferrite-garnet samples containing Zr, Th, Ce and Gd of the following composition: 1C - Ca2,5 Ce0,5 Zr2 Fe3 O12, 2C - Ca1,5 GdCe0,5 ZrFeFe3 O12, 1T - Ca2,5 Th0,5Zr2 Fe3 O12 and 2T - Ca1,5 GdTh0,5 ZrFeFe3 O12 are carried out. As a result of 57Fe Moessbauer study it is found that iron atoms in all investigated samples of garnets are in a trivalent state. The analysis of experimental Moessbauer spectra definitely specifies a various structural state of iron atoms in two investigated groups of samples: 1T, 1C and 2T, 2C. X-ray study have shown that 1T and 1C garnet samples crystallize in tetragonal space group I41/acd, but 2T and 2C samples crystallize in cubic space group Ia3d.
