摘要	A series of polycrystalline pyrochlore rare-earth titanate Ho(2-x)Cr(x)Ti(2)O(7) are synthesized in order to enhance the ferroelectricity of pyrochlore Ho(2)Ti(2)O(7). 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 Ho(2-x)Cr(x)Ti(2)O(7).
