Abstract:

The -Fe3N–CrN composite nanorods are synthesized by wet chemical technique. XRD-Rietveld analysis shows that -Fe3N and CrN crystallize in the space group P63/mmc and Fm3m with relative mass compositions 53% and 47%, respectively. The nanorods have an average diameter ∼30 nm and length ∼400 nm X-ray photoelectron spectroscopy (XPS) studies show the presence of nitrides and oxynitrides (Fe–O–N/Cr–O–N) at the surface and the presence of elemental Cr in CrN matrix along with the nitrides inside the nanorods, probed by the in-depth profile analysis. The magnetic interactions between the spins of ferromagnetic (FM) -Fe3N and antiferromagnetic (AF) CrN throughout the volume of the nanorods give rise to exchange bias coupling. The exchange bias phenomenon is influenced by the rough and non-uniform AF-FM interface and spin-glass-like ordering at lower temperatures. The ac susceptibility studies confirm the spin-glass-like ordering.
