Abstract :
In this paper a nominal composition of 1 at% Cr-doped ZnO nanorods is synthesized by a HHPMF method. Both the samples fabricated with and without high pulsed magnetic field exhibit well ferromagnetic behaviors at room temperature. The high pulsed magnetic field not only makes the nanocrystalline size uniform, but also enhances the saturation magnetisation of the Cr-doped ZnO diluted magnetic semiconductors.
