Abstract

BaTiO₃ (BTO)/La_2/3Ca_1/3MnO₃ (LCMO) bilayers were deposited on (001) SrTiO₃ substrates via pulsed-laser deposition (PLD) at pure oxygen atmosphere at a substrate temperature of 820 ^°C. For LCMO layers, magnetization measurements indicate that electric and magnetic properties are affected by the ferroelectric layer, which is attributed to crystallographic strains at the interface and the corresponding relaxation with increasing BTO layer thickness.
