Abstract:
GO:MoS₂ nanoparticle (NP) hybrid nanocomposite is prepared and studied structural, electronic and magnetic properties using X-ray diffraction, field emission scanning electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy and superconducting quantum-interface-device measurements. MoS₂-NP exhibited diamagnetic characteristic but GO:MoS₂-NP hybrid nanocomposite exhibited low temperature ferromagnetic characteristics. Field cooling and Zero field cooling characteristic exhibited divergence below ~280 K with increasing magnetic field. The saturation magnetic moment and coercivity of GO:MoS₂-NP hybrid nanocomposite is higher than GO that could be useful for low temperature magneticities and energy storage device application.
