英文摘要A series of polycrystalline pyrochlore rare-earth titanate Ho2-xCrxTi2O7 are synthesized in order to enhance the ferroelectricity of pyrochlore Ho2Ti2O7. A giant enhancement of polarization P from 0.54 mu C/m(2) at x=0 up to similar to 660 mu C/m(2) at x=0.4 is obtained, accompanied with an increment of ferroelectric transition point T-c from T-c similar to 60 K up to T-c similar to 140 K. A magnetic anomaly at T-c similar to 140 K together with the polarization response to magnetic field is identified, implying the multiferroic effect in Ho2-xCrxTi2O7.
