Annotation	Dielectric permittivity ϵ and polarization / electric field hysteresis loops of highly-resistive Li-doped non-relaxor Pb(Fe1/2Ta1/2)O3 ceramics obtained by one-step sintering of the mechanically activated mixture of starting oxides and Li2CO3 have been studied. Antiferromagnetic phase transition temperature TN ≈ 150 K was determined using Mossbauer spectroscopy studies at different temperatures. Though no anomalies in ϵ(T) curve at TN were observed, 1/ϵ(T) dependence exhibits change of the slope in the vicinity of TN. Anomalies in the temperature dependences of coercive field EC and derivative of the spontaneous polarization PS are observed near TN as well. These anomalies are attributed to magnetoelectric coupling.
