| 摘 要： | Using in situ electric-field-modulated anisotropic magnetoresistance measurement,a large reversible and nonvolatile in-plane rotation of magnetic easy axis of ~35° between the positive and negative electrical poling states is demonstrated in Co_(40)Fe_(40)B_(20)/(001)-cut Pb(Mg_(1/3)Nb_(2/3))O_3-0.25PbTiO_3(PMN-PT).The specific magnetoelectric coupling mechanism therein is experimentaiiy verified to be related to the synchronous in-plane strain rotation induced by 109° ferroelastic domain switching in the(001)-cut PMN-PT substrate.
