Abstract
Nanosized magnetic particles are the subject of research interest because of their potential in high density magnetic recording. In this paper, iron cobalt (FeCo) magnetic nanoparticles are synthesized by co‐precipitation and the magnetic and structural properties of the nanoparticles are investigated. The particles are formed through simultaneous reduction of Iron (III) chloride and cobalt (II) chloride in the presence of reducing agents. Growth of the particles size and shape due to various experimental conditions are investigated. Chemical synthesis has been successfully used to prepare monodispersed FeCo nanoparticles in the range of 10 to 20 nm. These nanoparticles are superparamagnetic at room temperature. The size and structure variations are analyzed by Transmission Electron Microscopy (TEM) and X‐Ray Diffractions (XRD). The magnetic properties of the nanoparticles are characterised by saturation magnetization, remanent magnetization and coercivity from hysteresis loop by Vibrating Sample Magnetometer (VSM).
