Bimetallic nanoparticles (NPS), composed of two different metals have drawn a greater interest than the monometallic nanoparticles from both scientific as well as technological point of view. Constituting metals and their nanometric size determine the properties of the bimetallic nanoparticles We are making magnetic nanoparticles and we specially focus on iron based nanoparticles. Magnetic nanoparticles are a class of nanoparticle that can be manipulated using magnetic fields. Such particles commonly consist of two components, a magnetic material, often iron, nickel and cobalt, and a chemical...
