Keywords:multiferroic, 0.7BaTiO3-0.3Pr0.65Ca0.35MnO3, Electrical response for magnetic field

Core-shell structure of 0.7BaTiO₃-0.3Pr_0.65Ca_0.35MnO₃ was synthesis by chemical method and characterized by XRD, SEM and, EDS. Temperature dependence of electrostatic capacity increase with magnetic field 280 mT. This phenomenon is reversible with magnetic field. BaTiO₃ and Pr_0.65Ca_0.35MnO₃ do not show this phenomenon. This phenomenon may be due to the multiferroic between piezoelectric and CMR effect through strain.
