%T Electric-field control of nonvolatile magnetization in Co 40Fe 40B 20/Pb(Mg 1/3Nb 2/3) 0.7Ti 0.3O 3 structure at room temperature
%V 108
%X We report a large and nonvolatile bipolar-electric-field-controlled magnetization at room temperature in a Co 40Fe 40B 20/Pb(Mg 1/3Nb 2/3) 0.7Ti 0.3O 3 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°ferroelastic domain switching and the absence of magnetocrystalline anisotropy in Co 40Fe 40B 20. This work provides a route to realize large and nonvolatile magnetoelectric coupling at room temperature and is significant for applications. © 2012 American Physical Society.
