研究了XY类完美三角晶格反铁磁体RbFe(MoO4)2在高达14T的磁场下的铁电性，它在低场120结构相P1和P2中表现出沿c轴的磁感应铁电极化。实验证实，B||a的RbFe(MoO4)2的高场P4/P5相是非铁电的。结果表明，该系统低场相的铁电性是由面内自旋手性驱动的。
Ferroelectricity was studied in magnetic fields up to 14 T on the XY-like perfect-triangular-lattice antiferromagnet RbFe (MoO 4) 2, which exhibits a magnetically induced ferroelectric polarization along the c axis in the low-field 120 structure phases P1 and P2. We have experimentally confirmed that the high-field P4/P5 phases of RbFe (MoO 4) 2 for B|| a are nonferroelectric. The results favor the scenario that the ferroelectricity in the low-field phases of this system is driven by the in-plane spin chirality.
