摘要: Coelectrodeposition of Ni with multiwall carbon nanotubes (MWCNTs) was successfully carried out by noncovalent functionalization. Microstructure and magnetic properties Ni-matrix nanocomposites films were investigated in a range MWCNTs content from 2% to 5.1%. The MWCNT controlled current density concentration the solution. composite exhibit polycrystalline microstructure having different texture factors along (111) (200) crystallographic orientations. show in-plane easy axis magnetization. However, coercivity squareness variations imply that magnetocrystalline anisotropy, grain size, morphology as well Ni/carbon nanotube interfacial microstrain play crucial roles magnetization process.
