چکیده:

NiCoxMn2-xO4 (x= 0, 0.4, 0.8, 1.2, 1.6) thermistors nanopowders have been synthesized by the auto-combustionmethod atlowtemperatures. The size and morphology ofthe calcinated powders have beeninvestigated using XRD andTEMtechniques.Theaverageparticlesizewasestimatedtobeabout65nmindiameterswiththecubicphase.Theformation of spinel structure of powders has been studied by Fourier transform infrared (FTIR) spectroscopy.
