Abstract Scope |
We will present our recent work in developing transition metal based hard permanent magnet using nanostructured materials. The ongoing investigations will focus on promising candidate materials of the type {Fe-Co}-X-Y (X = other 3d or 4d metals and Y= B, C, P or N) to develop high saturation magnetization materials that can be stabilized in tetragonal or hexagonal structures. For example, introduction of tetragonal distortion into the nanostructure of FeCo alloys yields materials possessing high values of magnetocrystalline anisotropy, coercivity and saturation magnetization. The first step towards this work, we experimentally synthesized anisotropic Co nanostructures by chemical synthesis approach (polyol process). Magnetic properties of the high-aspect-ratio nanostructures is enhanced by effectively utilizing the magnetocrystalline and shape anisotropy of these high magnetic moment materials. In next step critical Co will be substituted by Fe during the process. The effect of experimental synthesis parameters on morphology and magnetic properties will be discussed. |
