- Abstract
- Magnetic multiferroics TbMn2O5 shows rich magnetic phases that are strongly coupled to multiple electrical phases. Herein, we report that Fe substitutions in TbMn2O5 can selectively and completely suppress the lower-temperature anti-polar phase, whereas the higher-temperature ferroelectric phase is almost intact down to T approximate to 10K. Neutron diffraction on the single crystalline TbMn2-xFexO5 (x approximate to 0.06) shows that the commensurate magnetic phase persists down to T approximate to 1.7 K, indicating that the commensurability, which is responsible for the exchange-striction mechanism, plays a deterministic role on the ferroelectric polarization in TbMn2O5.
