Two‐phase CoFe 2 O 4 and BaTiO 3 (BTO) nanocomposites were fabricated by a solid‐state reaction. Following a similar process in a reducing environment, we have prepared Ni–BTO, a hybrid metal–ceramic nanocomposite with a nanorod grain morphology. We discuss the growth mechanism and demonstrate that our metal–ceramic nanorods are magnetic. Ni foil can reach saturation magnetization at magnetic fields of 700 G, whereas the Ni–BTO nanorods need 3000 G. In the future, this method may offer a convenient and inexpensive way to fabricate new types of multiferroic materials.
