Sažetak
The magnetoelectric materials have been studied due to the scientific challenges and the very promising possibility of applications in electronic devices. Bismuth ferrite (BFO) is one of the few room temperature magneto- electric multiferroics. The problem with bulk ceramic form of BiFeO 3 is low net magnetic moment of its ordered antiferomagnetic phase. To disturb the antiferromagnetic order and induce bigger magnetic moment, BFO is often doped with different elements, usually heavy rare earth elements or transition metal ions. The influence of Ho and Ag doping on the crystal structure and magnetic properties of bismuth ferrite nanopowders was investigated. 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 Ho 3+ and Ag + ions in the BiFeO 3 crystal lattice, where Ho 3+ substitute Bi 3+ ions and Ag + substitute Fe 3+ 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). Generally, magnetic response increases with doping, producing also stronger irreversibility in both temperature dependence of magnetization and hysteresis loops.
