✦ Synopsis

Synthesis and structural features of the relaxor ferroelectric PbMg , ,zNb,,,O,, the structural analogue PbMn,,,Nb,,,O, as well as the related phase PbMg, ,4Mn , ,,Nb,,,O, are described. It is shown that pure phases are only obtained when accurate experimental conditions and appropriate precursors are used. The magnetic and dielectric properties are characterized.

Investigations on the thermochemical reactivity of these phases reveal that metal selective reduction/ reoxidation processes, as well as phase segregations, take place.
