摘要: The effect of diamagnetic dilution the Fe sublattice on structural and magnetic properties double perovskite Sr{sub 2}Fe{sub 1-x}Ga{sub x}ReO{sub 6} (0 =}0.4 is detected by x-ray analysis accompanied observation a magnetically ordered paramagnetic phase in corresponding Moessbauer spectra. Below 20% Ga content, statistically dilutes -Fe-O-Re-O-Fe- double-exchange pathways. Phase separation begins at substitution; between 40% ofmore » Ga-based does not contain any Fe. Fe-containing, cubic phases which can be spectroscopy first appear for x=0.4.« less
