In this paper we report on the fabrication of a spintronic device based on multiwalled carbon nanotubes functionalized/coupled with a rare earth element complex. The spin valve behavior is verified by magneto-resistance fluctuations at low temperatures. We report the magneto-transport features of spin valve devices based on multiwalled carbon nanotube covalently functionalized with a gadolinium complex. The switching is encoded in the composite from which devices are fabricated by di-el ectrophoresis. The magnetic field dependen t electronic transport characteristics are investigated through the Cryogenic high field measurement system at 300 mK. Structural characterization of the material through transmission and scanning electron microscopy and Raman spectroscopy of the pristine and composite is done. The electronic transport shows a magnetic field dependence which is characteristic of spin valve at 300 mK and furthermore this spin valve feature is temperature dependent. Keywords: carbon nanotube, spintronic, device, magnetoresistance, low temperature |
