Abstract
Enhanced saturation magnetization was observed in granular nanostructured Ni/[Cu(II)–O–C] films deposited by the nonaqueous, electroless polyol process. The saturation magnetization of Ni–Cu complex films at room temperature was 112 emu/g, which was about two times that of bulk Ni (54.4 emu/g). It is suggested that the enhancement was caused by the magnetic interaction between the Ni particles and the amorphous Cu(II) complex. The observed shifted Curie temperature, large anisotropy field, and strong temperature dependence of saturation magnetization support this argument.
