Abstract

A report on chemical synthesis of dispersed SmCo₅ nanoparticles was presented. Transmission electron microscopy (TEM), electron diffraction, and x-ray photoelectron spectroscopy (XPS), indicated the size of the nanoparticles as 6-8 nm in diameter with a SmCo₅ composition. It was found that the magnetization measurements of the nanoparticles revealed superparamagnetism, which was blocked for temperatures below ∼110 k. It was suggested that high magnetocrystalline anisotropy constants (K_u) to be ∼2.1×10⁶ erg/cm³ for the as-prepared particles.
