Abstract

The structural, vibrational, and magnetic properties of well prepared Bi_1-xHo_xFeO₃ (x=00.175) powders are investigated by combining X-ray diffraction, Raman scattering, and magnetometry measurements. A structural symmetry breaking from the rhombohedral R3c to orthorhombic Pnma between x=0.10 and 0.125 is identified from the X-ray and Raman measurements, accompanying a ferroelectricparaelectric phase transition. The remnant magnetization of Bi_1-xHo_xFeO₃ is enhanced before approaching the ferroelectricparaelectric phase boundary, and then it slightly decreases until x=0.175. Such enhancement (0≤x≤0.10) is suggested to result from the destruction of the spin cycloid structure. The decrease in the remnant magnetization with higher substitution concentration is due to the further destruction in the space modulated spin structure allowing a more perfect antiferromagnetic ordering
