Magnetic properties: The room temperature (RT) M–H curves for
undoped BFO, BDFO–BTO and BDFCO–BTO composites are shown in
Fig. 2. Both the composites exhibit typical ferromagnetic (FM)
characteristics and well saturated M–H curves. The measured magnetic parameters are summarized in Table 1. Undoped BFO signals a
very weak canted antiferromagnetism.
