•Theoretical magnetic value of the samples was calculated.•The experimental value of the magnetism was greater than the theoretical value.•The effect of the crystallite sizes on the magnetism was eliminated by calculating the crystallite sizes of BLFO.•The BLFO contributed to the magnetic moment through the magnetoelectric coupling.
In this work, a solid phase reaction method was used to fabricate (1−x)Bi0.85La0.15FeO3–xCoFe2O4 (x=0.1, 0.2, 0.3, 0.4) composite powders. X-ray diffraction patterns showed that no chemical reaction occurred between the separate Bi0.85La0.15FeO3 and CoFe2O4 phases and indicated that the powder samples had two distinct phases with a CoFe2O4 spinel phase and a Bi0.85La0.15FeO3 perovskite phase. The average crystallite sizes of the Bi0.85La0.15FeO3 in the composite powder were almost unchanged as the CoFe2O4 content was increased. By comparing the experimental and theoretical values for the magnetization, we found that the Bi0.85La0.15FeO3 phase contributed to the magnetization of the composite powders. In addition, it also provides a new way to prove the existence of magnetoelectric coupling in the sample.
