dc.descriptionPresented here are the results of magnetic data that reveal that both Pb-based perovskites samples, Pb(Fe1/2Nb1/2)O-3 (lead iron niobate - PFN) and Pb(Fe2/3W1/3)O-3 (lead iron tungstate - PFW), exhibit a change in magnetic ordering from paramagnetic (PM) to weak ferromagnetic state at high temperature: a weak ferromagnetic order occurs in the samples around 530K. The experimental results suggest a possible involvement of the Pb ions into the superexchange of antiferromagnetic (AFM) phase.
