摘要

Understanding the microscopic mechanism of magnetoelectric coupling is of fundamental importance for the rational design of multiferroics. Herein, the magnetoelectric coupling effect in the metal-organic frameworks of [NH_2(CH_3)_2]_n[Fe~(III)Fe~(II)(HCOO)_6]_n (1) was investigated, respectively, through measuring the dielectric properties and ferroelectric polarization of single-crystal 1 along different crystal axes under external magnetic fields. Analysis on the magnetic structure of 1 reveals that the defect in the Fe~(II)-Fe~(III) sublattices plays a key contribution to the magnetoelectric coupling of 1, providing a unique insight into the magnetoelectric coupling effect of MOFs-based multiferroics.
