摘要	The effects of Y-doping on the magnetic, dielectric and ferroelectric properties of EuMnO3 were carefully investigated through a series of polycrystalline Eu1-xYxMnO3 (x = 0, 0.15, 0.25, 0.3 and 0.5) samples prepared by solid state reaction. The Y-doping reduces the A-site ionic size and then the Mn-O-Mn bond angle. It is postulated that upon the doping, the magnetic ground state firstly changes to a conical spin order at x = 0.15 and then a spiral spin order for higher doping. The ferroelectric transitions appear at the conical and spiral spin order transition points similar to 25 K, and a polarization similar to 90 mu C/m(2) is achieved in sample with x = 0.25.
