AbstractDielectric permittivity ϵ and polarization / electric field hysteresis loops of highly-resistive Li-doped non-relaxor Pb(Fe Ta )O ceramics obtained by one-step sintering of the mechanically activated mixture of starting oxides and Li CO have been studied. Antiferromagnetic phase transition temperature T ≈ 150 K was determined using Mossbauer spectroscopy studies at different temperatures. Though no anomalies in ϵ(T) curve at T were observed, 1/ϵ(T) dependence exhibits change of the slope in the vicinity of T . Anomalies in the temperature dependences of coercive field E and derivative of the spontaneous polarization P are observed near T as well. These anomalies are attributed to magnetoelectric coupling.
