abstract = {The transition between insulator and metal conductor
states, induced by oxygen non-stoichiometry, was studied for
NaNbO3 : Mn crystals. Conditions for an optimal reduction
were determined on the basis of TGA tests. The temperature
dependencies of the resistance measured on the macroscale
showed that the transition from thermally activated to
metallic features depends on the level of oxygen deficiency.
The LC-AFM measurement exhibited non-homogeneous electric
resistance on the nanoscale. We ascribed the local
insulator-metal transition to changeover in the electronic
state of the Nb ions occurring in filaments. The Mn dopant
stabilised the induced oxygen non-stoichiometry and the
metallic conduction down to room temperature.},
