Experimental study and thermodynamic analysis are conducted to identify a process window for the preparation of BaTiO 3 –Ni ferroelectric–ferromagnetic composites. A tiny amount of Ni solutes (<0.5 mol%) can play a key role in the preparation of the composites. The Ni solute acts as an acceptor that enhances the reduction resistance of BaTiO 3 . Owing to the presence of Ni acceptors, dense BaTiO 3 –Ni composites can be prepared by sintering above 1330°C in an atmosphere of 1 Pa oxygen partial pressure.
