Control of magnetic domain wall motion by electric fields has recently attracted scientific attention because its potential for logic and memory devices. Here, we report on a new driving mechanism that allows in an applied field without the concurrent use or spin-polarized current. The is based elastic coupling between ferroelectric walls multiferroic heterostructures. Pure electric-field driven demonstrated epitaxial Fe films BaTiO$_3$ with in-plane out-of-plane polarized domains. In this system, fully reversible velocity varies exponentially as function strength.
