Copper ferrite (CuFe 2 O 4 ) nanoparticles were prepared in alkaline solutions containing Cu(NO 3 ) 2 ·6H 2 O and Fe(NO 3 ) 3 ·9H 2 O with the pH of 6-12 by microwave-hydrothermal method. The as-prepared products characterized by XRD were specified as cubic CuFe 2 O 4 phase. Average sizes of the CuFe 2 O 4 nanoparticles calculated by Scherrer formula are in the same range as those obtained by TEM analysis. FTIR shows main transmittance band at 585 cm -1 , corresponding to stretching mode of tetrahedral complexes. Saturation magnetization, remanence and coercivity were increased with increasing in the particle-size and crystalline degree of the nanoparticles.
