Abstract

The influence of size reduction on the magnetism of CoRh on a system of isolated nanometric spherical bimetallic ultrafine particles embedded in a polymer matrix, was discussed. It was found that the particles with a mean diameter of 1.65 (±0.1) nm displayed a value of 2.38 μB per CoRh unit. The analysis showed that the alloying and size reduction played a cooperative role in the enhancement of magnetic saturation in this system.
