AB  - Bismuth ferrite, BiFeO3, was doped with a wide range of concentrations (0-30%) of Gd in order to investigate structural, ferroelectric, and magnetic properties and their correlation. Powder samples of Bi1-xGdxFeO3 (x = 0.00-0.30) were prepared using the hydro-evaporation synthesis method. Sintering process at 870 degrees C for 6 h of as-prepared, Gd doped BiFeO3 powders resulted in ceramic samples with relative densities in the range of (74-86) %. XRD analysis revealed that Bi1-xGdxFeO3 samples (x = 0.00-0.09) crystallized in rhombohedral phase; Bi1-xGdxFeO3 samples (x = 0.10-0.20) contained both rhombohedral and orthorhombic phases, while Bi1-xGdxFeO3 (x = 0.30) sample contained only the orthorhombic phase. The structural parameters obtained after Rietveld refinement for single-phase Bi1-xGdxFeO3 ceramic samples and microstructure image analysis were correlated with the results of ferroelectric and magnetic measurements. Bi1-xGdxFeO3 (x = 0.0625, 0.075, 0.09) samples showed improved ferroelectric properties and reduced leakage current density in comparison with undoped BiFeO3. Gradual increase in Gd content in BiFeO3 led to enhanced magnetic responses and weak ferromagnetic behavior.

AB  - 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) magnetization 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.
