The dielectric permittivity and resistivity have been measured simultaneously as a function of magnetic field in Pr<Subscript>1-x</Subscript>Ca<Subscript>x</Subscript>MnO<Subscript>3</Sub script> crystals with different doping. A huge increase of dielectric permittivity was detected near percolation threshold. The dielectric and conductive properties are found to...<//sub></subscript></subscript></subscript>
