Sažetak
Bismuth ferrite (BiFeO3) is one of the most studied multiferroic systems mainly because of BiFeO3 material possesses both antiferromagnetic and ferroelectric properties observed at room temperature, which opens great possibilities for industrial and technological application. The influence of Ho doping on the crystal structure and magnetic properties of bismuth ferrite (BFO) nanopowders was investigated. BiFeO3 and Bi1-xHoxFeO3 ultrafine nanopowders were synthesized by the hydrothermal method. Here we use simple, low-cost and energy-saving hydrothermal method, which has advantages over the conventional methods. The diffraction pattern was recorded at room temperature and atmospheric pressure in the absence of any re-heating of the sample. A fitting refinement procedure using the Rietveld method was performed which showed the incorporation of Ho3+ ions in the BiFeO3 crystal lattice, where they substitute Bi3+ ions. All the samples belong to R3c space group. Magnetic behavior of synthesized materials was investigated by SQUID magnetometer in wide temperature interval (2-800 K). Temperature dependence of magnetization shows antiferromagnetic transition at TN~630 K and below this temperature weak ferromagnetism is observed, which becomes enhanced with the Ho doping.
