Magnetic and optical properties of FeAu synthesized through polyol process. P. 19

Polyol process is an environment friendly and cost effective synthesis method to obtain highly reducing metals such as Au and Ag whereas co-reduction of metals to obtain alloys are challenging. We report the successful synthesis of FeAu and present their optical and magnetic properties. The XRD analysis showed fcc structure and a Curie temperature of 400 °C was obtained from the thermomagnetic analysis. The room temperature magnetic measurements revealed a saturation magnetization of 15 emu/g. The optical nature of the compound was probed by UV-Visible spectroscopy which showed a blue shifted plasmon resonance peak at 550 nm. (author)
