Abstract

Heterostructures were fabricated by growing Pr_0.6Ca _0.4MnO₃ (PCMO) films on Pb(Mg_1/3Nb _2/3)_0.7Ti_0.3O₃ substrates. It was shown that the magnetizations of the samples can be tuned dramatically by electric fields via piezostrain and the effect is dominated by the change in phase separation. More interestingly, the electric-field control of magnetization is nonvolatile, manifesting a memory effect of strain. The results were discussed by considering the effect of electric-field-induced strain on the energy landscape of PCMO and the resultant change in phase separation. This work is helpful for exploring the evolution of phase separation with well-controlled strains and the magnetoelectric coupling effect.
