Abstract

The authors present the structure transformation and magnetic properties of Bi1-x Lax Fe O3 (x=0.0-0.15) ceramics prepared by a conventional solid-state reaction processing. Magnetic measurements reveal that remnant magnetization of 15% La-doped BiFe O3 has enhanced about 20 times as compared to pure BiFe O3. It is the structural phase transition (R3c-C222) near x=0.15 that destructs the spin cycloid, and thus enhances the ferromagnetic properties significantly. In these Bi1-x Lax Fe O3 ceramic samples, besides the known antiferromagnetic Ńel temperature TN1 ∼615 K, another Ńel temperature TN2 ∼260 K can be observed due to the trace impurity phase of Bi2 Fe4 O9 in these ceramic samples.
