Coexistence of Ferroelectricity and Ferromagnetism in Fullerene-Based One-Dimensional Chains.

ABSTRACT: One-dimensional (1D) magnetoelectric multiferroics are promising multifunctional materials for miniaturized sensors, actuators, and memories. However, 1D materials with both ferroelectricity and ferromagnetism are quite rare. Herein, using first-principles calculations, a series of fullerene-based 1D chains, namely U₂ C@C₈₀ -M (M = Cr, Mn, Mo, and Ru) 1D chains with both ferroelectric (FE) and ferromagnetic (FM) properties is designed. Compared to individual U₂ C@I_h (7)-C₈₀ , the spontaneous polarization (Ps) in 1D chains is enhanced by about two to four times owing to the interaction between U₂ C@I_h (7)-C₈₀ fullerene and M (M = Cr, Mn, Mo, and Ru) atoms. Meanwhile, the introduction of transition metal
