Abstract: Using first-principles calculations with dispersion-corrected DFT-D2 method, magnetic moments and magnetic anisotropy energy flexibly by the ferroelectric polarization of PVDF were manipulated.In particular, by charge injection method, the spin-dependent screening of the ferroelectric polarization is proved to be responsible for this manipulation rather than the chemical bondings.The study is beneficial to electric-field controlled magnetic data storage.
