Relaxor ferroelectrics – open questions<br />
Atomistic nature of relaxor behaviour<br />
Can we tune relaxor properties<br />
by tailoring polar nanoclusters?<br />
nanoclusters?<br />
• Which is the driving force for nucleation of polar nanoclusters at HT?<br />
• What is the reason for suppression of ferroelectric long-range ordering at LT?<br />
local electric fields due to charge imbalance<br />
local elastic fields due to local structural distortions<br />
