On the control of magnetic anisotropy through an external electric field

Abstract:
The effect of an external electric field on the magnetic anisotropy of a single-molecule magnet has been investigated, for the first time, with the help of DFT. The application of an electric field can alter the magnetic anisotropy from "easy-plane" to "easy-axis" type. Excitation analysis performed through time-dependent DFT predicts that the external electric field facilitates metal to π-acceptor ligand charge transfer, leading to uniaxial magnetic anisotropy and concomitant spin Hall effect in a single molecule.
