Oscillatory and Chaotic States of the Electrical Conduction in Barium Sodium Niobate Crystals

Abstract

Evidence is presented for oscillatory and chaotic behavior of the electrical conduction measured in barium sodium niobate single crystals at elevated temperatures. Analysis of the chaotic state verifies the existence of a strange attractor, whose dimension and entropy are determined. The observations indicate a Ruelle-Takens-Newhouse scenario.
