Dielectric properties are reported for lead magnesium niobate (PbMg 1/3 Nb 2/3 /O 3 ) ceramics which were prepared as single phase (i.e., without pyrochlore) with an improved technique. Dielectric constants of 18000 for pure PMN and 31000 for PMN with 10% PbTiO 3 were achieved; these values are 50% ...
