Abstract :
The authors present some preliminary results aimed at exploring the potential of lead magnesium niobate (PMN) as an energy storage dielectric. In particular, relative permittivity and resistivity were studied as a function of electric field. The PMN dielectrics were evaluated as capacitor materials for pulse discharge applications. A series of compositions were prepared and compared to pure and commercial strontium titanate dielectrics. The comparison results are discussed
