Structure and magnetodielectric properties of composite ceramics based on lead ferroniobate

In this research, the structural, electrodynamic, and magnetodielectric properties of composite ceramic materials based on lead ferroniobate Pb(Fe$_{0.5}$Nb$_{0.5}$)O$_{3}$ have been studied. The experimentally obtained temperature and frequency dependences of the dielectric constant indicate the presence of a low-temperature polar state, large values of the dielectric constant in the microwave range, and high electrical conductivity of the materials studied.
