Control of the magnetic anisotropy under different strain states is important for the manipulation of magnetization in flexible spintronic devices. Here, the electric field control of magnetic anisotropy was investigated in flexible Fe81Ga19(FeGa)/polyvinylidene fluoride multiferroic heterostructures under different compressive strains. The initial uniaxial magnetic anisotropy is enhanced with increasing the compressive strain. When the strain is larger than 0.06%, the electric field can only change the strength of the magnetic anisotropy but cannot change its direction. When the strain is smaller than 0.06%, the electric field of 267 kV/cm can reorientate the easy axis by 90°. The present results may be helpful for designing flexible multiferroic devices with a suitable initial strain in order to realize the 90° reorientation of the magnetization.
