AbstractThe effect of high-energy mechanical activation on dielectric and magnetic properties of PbFeTaO (PFT) multiferroic was studied. Mössbauer studies have shown that the Neel temperature T of the antiferromagnetic phase transition in PFT powders can be changed substantially by mechanical activation and subsequent annealing. The increase of T by more than 70 K, as compared to PFT single crystal, was achieved in the mechanically activated PFT powder annealed at 700°C. Dielectric studies have shown that in contrast to ceramics obtained by usual sintering, PFT ceramics fabricated by sintering of the mechanoactivated powder does not show the relaxor-like behavior.
