Formation and magnetic properties of InFeP:Ag nano-rods fabricated with noble metal Ag using ion milling method.

The formation including density, and height of InFeP:Ag nano-rods doped with noble metal Ag using ion milling method was preponderantly determined from TEM and XRD analyses. We investigate especially the enhanced ferromagnetism of the well aligned InFeP:Ag nano-rods. AES and XPS measurements were carried out in order to investigate the incorporation of Ag and to verify the local chemical bonding of InFeP:Ag nano-rods. The variation of FWHM for DCRC and TAD peaks demonstrates that noble metal Ag is incorporated into InFeP:Ag nano-rods. The noticeable ferromagnetic signature (M-H curve) of the InFeP:Ag nano-rods is observed and Tc persists up to near 350 K (3.9 × 10-4 emu/g) from temperature - dependence magnetization (M-T curve) measurements. This study suggests that the InFeP:Ag nano-rods should be a potential candidate for the application of spintronic devices.
