摘要：

Magnetoelectric multiferroics are attractive materials for the development of low-power electrically controlled spintronic devices. Here we report the optimization of the exchange bias as well as the giant magnetoresistance effect (GMR) of spin valves deposited on top of BiFeO3-based heterostnictures. We show that the exchange bias can be electrically controlled through a change in the relative proportion of 109 degrees domain walls and propose solutions toward a reversible process.
