Lead magnesium niobate dielectrics for high-field applications

摘要

The authors present some preliminary results aimed at exploringthe potential of lead magnesium niobate (PMN) as an energy storagedielectric. In particular, relative permittivity and resistivity werestudied as a function of electric field. The PMN dielectrics wereevaluated as capacitor materials for pulse discharge applications. Aseries of compositions were prepared and compared to pure and commercialstrontium titanate dielectrics. The comparison results are discussed
