摘要/Abstract

摘要： 基于第一性原理计算,引入色散修正方法(DFT-D2),通过PVDF铁电极矩调控了铁磁层的磁矩和磁晶各向异性能.特别地,通过电荷注入方法,证实电控磁性源自铁电极矩的静电屏蔽而非化学成键.该研究将促进电场控制的磁存储技术的发展.

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.
