Abstract: MnCo2O4 magnetic nanocrystals was synthesized by one-step method used potassium permanganate (KMnO4), manganese acetate [Mn(Ac)2] and cobalt acetate [Co(Ac)2] as raw materials. The morphology, structure, composition and magnetic property of MnCo2O4 crystals were studied. The results showed that MnCo2O4 magnetic nanocrystals had a narrow size distribution of 80?120 nm and display perfect sheet shape with high crystallinity and good dispersity. MnCo2O4 nanocrystals exhibit good magnetic property with a high Curie temperature of 182 K.

Key words: manganese cobalt oxides, magnetic materials s, hydro-thermal synthesis, nanocrystalline, composite
