Bismuth ferrite, BiFeO3 is perovskite multiferroic often studied because of its
high ferroelectric and magnetic ordering temperatures, 1100 K and 630 K,
respectively. Despite its room temperature multiferroicity, pure BiFeO3 is of limited
technological importance, especially in bulk ceramic form, due to the
antiferromagnetic state with very low net magnetic moment. Doping of BiFeO3
could disturb the antiferromagnetic order and induce magnetically ordered state with
considerable magnetization coming from the uncompensated or canted spins.
Therefore, magnetic behaviour of BiFeO3 doped with the heavy rare earth elements
such as La, Yb and Gd, was investigated.
Compounds of BiFeO3 in which 10% of Bi atoms are substituted with La, Yb
and Gd were prepared using the hydro-evaporation synthesis. Magnetization of
polycrystalline samples in powder form was investigated in a broad temperature
range of 2–900 K. Splitting between the zero field cooled (ZFC) and field cooled
(FC) magnet...ization curves indicate development of the weak ferromagnetism below
the Néel temperature of around 610–640 K which is dependent on the composition.
Magnetic hysteresis loops measured at the low temperature (5 K), room temperature,
and high temperatures, just under and above transition temperature, also suggest the
weak ferromagnetic behavior with relatively high coercive field.
Complete magnetic results in full temperature range (2–900 K) clearly indicate
enhancement of the weak ferromagnetism after performed substitution with rare
earth elements La, Yb and Gd in bulk BiFeO3 ceramic.
