Effect of electric field on magneto-transport properties in La_2/3(Ca_0.6Ba_0.4)_1/3MnO₃/Pb(Zr_0.52Ti_0.48)O₃ laminated composite

The effects of electric field on the magnetization and Hall resistivity were investigated in a laminated composite consisting of polycrystalline perovskite La2/3(Ca0.6Ba0.4)1/3MnO3 (LCBMO) material and Pb(Zr0.52Ti0.48)O3 (PZT) ferroelectric ceramic. Upon applying an electric field (9 kV/cm) on the ferroelectric ceramic, the Hall resistivity change of the LCBMO layer is up to − 23%. The electric field-modulated Hall resistivity in LCBMO/PZT composite is attributed to the coaction of magnetization change and carrier concentration change, which result from stress-induced variation of both metal–insulator transition and ferromagnetic–paramagnetic transition.
