Structural, morphological and optomagnetic properties of GO/Nd/Cu-Mn ferrite ternary nanocomposite

Abstract

Graphene oxide (GO)/neodymium (Nd)/Cu 0·5 Mn 0·5 Fe 2 O 4 ternary nanocomposite was prepared by sonochemical method and modified Hummer's method. The crystal structure and structural parameter of Cu 0·5 Mn 0·5 Fe 2 O 4 (CMF) nanoferrites were changed with the addition of Nd 3+ and GO. Raman active modes of the GO and ferrite system were observed from Raman spectra. The surface oxidation state (C 1s, O 1s, Cu 2p, Mn 2p, Fe 2p, and Nd 3 d) and their respective binding energies of the prepared nanocomposite were discussed. Different surface morphologies were acquired for CMF, Cu 0·5 Mn 0·5 Fe 1.85 Nd 0.15 O 4 (CMNF), GO, and GO/Cu 0·5 Mn 0·5 Fe 1.85 Nd 0.15 O 4 (GCMNF) ferrite nanocomposites. The absorption of the Cu-Mn nanoferrite (red region) shifted into the blue region with the addition of Nd 3+ and GO. The magnetic parameters were changed with doping of Nd into CMF and GO in CMNF nanoferrite. It was found that the high anisotropy energy values of the CMNF and GCMNF ferrite nanocomposites could be used for electromagnetic wave-absorbing application.
