Dielectric properties, ionic conductivity and phase transitions in La2Mo2O9 ceramics

The dspersion dielectric permeability and ion conductivity of La 2 Mo 2 O 9 ceramics was studied. It was established that the observed low-frequency dielectric dispersion is due to relaxation effects related to high ion conductivity. It is shown that the phase transition in La 2 Mo 2 O 9 has charact...

Description
Summary:The dspersion dielectric permeability and ion conductivity of La 2 Mo 2 O 9 ceramics was studied. It was established that the observed low-frequency dielectric dispersion is due to relaxation effects related to high ion conductivity. It is shown that the phase transition in La 2 Mo 2 O 9 has characteristic features of a superionic phase transition.
