摘要：

We report a large and nonvolatile bipolar-electric-field-controlled magnetization at room temperature in a Co40Fe40B20/PbdMg(1/3)Nb(2/3))(0.7)Ti0.3O3 structure, which exhibits an electric-field-controlled looplike magnetization. Investigations on the ferroelectric domains and crystal structures with in situ electric fields reveal that the effect is related to the combined action of 109 degrees ferroelastic domain switching and the absence of magnetocrystalline anisotropy in Co40Fe40B20. This work provides a route to realize large and nonvolatile magnetoelectric coupling at room temperature and is significant for applications.
