Abstract

We report in situ manipulation of the in-plane strain εxx(BFMO) and coercive field EC(BFMO) of BiFe_0.95Mn_0.05O₃ (BFMO) films epitaxially grown on La_0.7Sr_0.3MnO ₃ film buffered 0.71Pb(Mg_1/3Nb_2/3)O ₃-0.29PbTiO₃ (PMN-PT) substrates. PMN-PT poling-induced strain is effectively transferred to BiFe_0.95Mn_0.05O ₃ films and enhances εxx(BFMO) and EC(BFMO), with a gauge factor (ΔEC(BFMO)/EC(BFMO))/(δεxx) ∼-25 and -326 for the BFMO(001) and BFMO(111) films, respectively. Based on the strain dependence of EC(BFMO), we established a quantitative relationship between EC(BFMO) and εxx(BFMO). Using ferroelastic strain of PMN-PT, we achieved reversible and non-volatile modulation of strain and EC(BFMO) of BFMO films, providing an approach for non-volatile and reversible turning of strain and physical properties of ferroelectric films.
