Abstract: Stress induction plays a special role in performance control for material science. So far, it has remained challenging to systematically investigate magnetoelectric effect under stress-mediated interaction. Here we constructed a magnetoelectric device with piezoelectric stress induction, in which the stress plays a crucial intermediate role during the controllable modification of the magnetic behavior transitions under the magnetic field or current pulse driven process. The compressive stress was found to make the above process easier and reduce energy consumption via changing the magnetic domain energy state. Meanwhile, both the domain distribution and domain-wall driven process are sensitive to stress intensity. Our magnetoelectric device integrated the advantages of voltage-stress and spin-current for the control of magnetic behavior transition with the help of micro-nano processing. For the stress-induced magnetic behavior in magnetic materials was directly imaged and quantificationally investigated, the complex interactions between stress, magnetic domain motion, magnetic field, and spin current have been clarified.
