ABSTRACT
Organic polymer-material-based magnets may have several attributes, such as low density, flexibility, processability at low temperatures, property modulation, solubility, biocompatibility, and semiconducting or insulating abilities. Magnetic materials are the backbone of modern digital technologies; of late, stretchable magnetoelectronics have gained substantial interest over the last few years because of their scope for exciting new applications offered by arbitrary surface geometries possible after fabrication. There are reports about the generation of organic molecular magnets through synthetic routes. Although much attention has been paid by researchers on the development of organic molecular magnets through chemical synthesis, but such synthetic methods are quite difficult to realize organic magnets. In this backdrop, magnetic materials have been prepared by embedding magnetic nanoparticles of transition metals, such as cobalt, iron, and nickel on different polymer matrices, such as polyvinyl alcohol (PVA), polymethylmethacrylate (PMMA) using ion beam sputtering (IBS) technique. Characterization of 96these magnetic materials has been made using instruments, such as grazing incidence X-ray diffraction (GIXRD), magneto optical Kerr effect (MOKE), and X-ray photoelectron spectroscopy (XPS) to understand the microstructural properties, chemical state of the nanoparticles and magnetic properties.
