Abstract
This work reports an experimental investigation of the ferroelectric character of magnetic phases of the orthorhombic Eu1−xY xMnO3 system at low temperatures. The temperature dependence of the polarization curves clearly reveals the existence of a re-entrant improper ferroelectric phase for x = 0.2 , 0.3 and 0.5. A ferroelectric phase is also stable for x = 0.4 , and we have no experimental evidence for its vanishing down to 7 K. From these and early results obtained using other experimental techniques, the corresponding ( x , T ) phase diagram was traced, yielding significant differences with regard to the ones previously reported.
