Characterization of the physical properties of NdNiO3 nanotubes.

Abstract

Neodymium nickelate (NdNiO3) is a correlated oxide that exhibits a metal–insulator transition (MIT) close to 200K and is of interest for advanced electronics and optoelectronics. In this work, we have synthesized NdNiO3 nanotubes using a template-assisted method. For this, precursor solution with stoichiometric amounts of Nd-Ni was prepared by polymeric precursor route, than this solution was deposited in commercial anodized aluminum mesoporous membranes. All samples were heat treated at temperatures ranging from 350 to 750°C under oxygen pressure of 1 and 100 bar. The samples were characterized by X-ray diffraction, scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and magnetization as a function of temperature (M(T)).FAPESPCAPESUFAB
