The 1:2 ordering in Ba(Ni{sub 1/3}Nb{sub 2/3})O{sub 3} ceramics sintered at 1,350--1,500 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 1,350--1,400 C, whereas Raman spectroscopy discerns the 1:2 ordering for all the samples. Similar results have been obtained for Ba(Zn{sub 1/3}Nb{sub 2/3})O{sub 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{sub 1/3}{prime}{sup II}B{sub 2/3}{double_prime}{sup V})O{sub 3}-type complex perovskite compounds.
