Interface physics in oxides heterostructures is pivotal material's science. Domain walls (DWs) ferroic systems are examples of naturally occurring interfaces, where order parameter neighboring domains modified and emerging properties may develop. Here we show that electric tuning ferroelastic domain SrTiO3 leads to dramatic changes the magnetic structure a layer (La1/2Sr1/2MnO3) epitaxially clamped on substrate. We intimately connected existence polar regions at twin boundaries SrTiO3, developing , can be electrically modulated. These findings illustrate by exploiting responsiveness DWs nanoregions external stimuli, even absence any contribution, prominent adjustable macroscopic reactions layers obtained. conclude DWs, known exist other materials, used trigger tunable responses lead new ways for manipulation interfacial properties.
