Structural and magnetic study of bimetallic Co1−xRhx particles

Abstract We studied the structural and magnetic properties of cobalt-rhodium nanoparticles dispersed in a polymer matrix. It is shown that the structure depends on the composition, high cobalt content leading to a non-periodic structure. Magnetic measurements confirm the dispersion, particle size, and bimetallic character of the particles. Evidence is given of enhanced magnetisation for the composition x =0.5.
