Abstract

FePd₃-type alloys have attracted strong interest due to their unusual pressure-induced Invar behaviour characterized by anomalously low thermal expansion properties. However, little is known about the factors controlling their magnetization properties. Here we present a chemical vapour deposition approach which allows the encapsulation of FePd₃ alloys into a spherical type of carbon nanomaterial consisting of concentrically arranged distorted-carbon-layers. A dependence of the magnetic properties of this soft ferromagnetic phase on the crystal-grain-size is found by comparing the results in the present study with those reported in literature. The fabricated samples are characterized in detail by electron microscopy, x-ray and electron diffraction and magnetometry.
