Formation of iron nanoparticles on quartz substrate using dense plasma focus device

Abstract

Fabrication of nanoparticles and nanostructured materials is at the heart of modern nanoscience. In the present work, we are reporting the fabrication of Iron nanoparticles making use of high temperature, high density, and extremely non equilibrium pulsed plasma produced in 3.3 KJ Mather type Dense Plasma Focus (DPF) device. The Iron nanoparticles were deposited on quartz substrate at a distance of 5 cm above the ion source. The Iron nanoparticles are characterized structurally using X-ray diffractometer and topographically using Atomic force microscopy (AFM). The magnetic property was investigated using Magnetic Force Microscopy (MFM). It is found that these nanoparticles have a dimension in the range of 20-60 nm size and are magnetic in nature.
