The 1:2 ordering in Ba(Ni 1/3 Nb 2/3 )O ceramics sintered at 1350‐1500°C has been investigated by using XRD and Raman spectroscopy. Both of the techniques show that the degree of the 1:2 ordering decreases as the sintering temperature increases. However, XRD discerns the 1:2 ordering only for the samples sintered at 1350‐1400°C, whereas Raman spectroscopy discerns the 1:2 ordering for all the samples. Similar results have been obtained for Ba(Zn 1/3 Nb 2/3 )O 3 ceramics, where only the temperature range is slightly different. It is demonstrated that Raman spectroscopy can be a useful tool for probing of the 1:2 ordering in the A(B' II 1/3 B” V 2/3 )O 3 ‐type complex perovskite compounds.
