Preparation route of low-dimensional spin-peierls magnetic Cu 1-x Ni x GeO 3 in a form of nanorods
Abstract
A new approach for synthesis of Cu 1−x Ni x GeO 3 (x = 0÷0, 15) in form of nanorods is developed. Analysis of the lattice evolution with Cu(II) percentage showed a change of the cell parameters that corresponds to the theoretical simulation completely. Doping with nickel leads to a rise of dopant concentration in the solid solution.
