Extremely reduced loss tangent with retaining ultra high dielectric permittivity in Mg-doped LaSrNiO ceramics.

An extremely reduced loss tangent while retaining ultrahigh dielectric permittivity can be successfully obtained in LaSrNiO ceramics by doping with Mg ions. A single phase of LaSrNiO was detected in all the sintered ceramics, while the lattice parameters increased with increasing doping concentration, indicating that Mg ions can enter the Ni sites. A highly dense microstructure is achieved.

Significant enhancement of dielectric permittivity and percolation behaviour of La Sr NiO/poly(vinylidene fluoride) composites with different Sr doping concentrations.

The percolation behaviour and dielectric properties of La Sr NiO (LSNO)/poly(vinylidene fluoride) (PVDF) composites with different Sr doping concentrations were investigated. The semiconducting LSNO filler particles with = 0.2 (LSNO-1) and = 0.
