Effects of lead vacancies on the spontaneous relaxor to ferroelectric phase transition in Pb[(Mg1/3Nb2/3)0.9Ti0.1]O3

A study was conducted on the influence of lead vacancies on the R-nFe transition in a Pb(B'1/3B'2/3)O3 compound. The results indicate that both the relaxor behavior and the phase transition are strongly dependent on the lead vacancies content. Moreover, a change in the polar clusters size resulting from lead vacancies formation weakens the dipolar interactions and inhibits the spontaneous relaxor to ferroelectric phase transition.
