Abstract
Ferromagnetic properties of Fe-doped ZnTe Nano-rods have been studied by employing Superconducting Quantum Interference Device (SQUID) measurement. The Scanning Electron Microscopic (SEM) and Transmission Electron Microscopic (TEM) image of the Fe doped ZnTe reveals a rod-shaped morphology. The EDAX spectra is obtained to trace the elements present in the Fe doped ZnTe Nano-Rods. The analysis of the XPS spectra of the Fe doped ZnTe nano-rods has been conducted by considering the binding energy values of the elements present in the Fe doped nano-rods. The XPS analysis reveals the Fe2+ oxidation state of Fe in ZnTe Nano-Rods. The SQUID measurement reveals the ferromagnetism at 300 K, 150 K and even at 5 K. Also, the ferromagnetic ordering is confirmed from the FC and ZFC curves obtained at 100 Oe. This elucidates that these Fe doped ZnTe Nano-Rods is a suitable material for spintronic device applications.
