Memristive systems can be used for the generation of higher harmonics [1]. We investigated the second and higher harmonics generation by means of a passive circuit with a sinusoidal input voltage source in series with a load resistor and a single memristor (Au/BiFeO3/Pt) that exhibits nonvolatile bipolar resistive switching. We found that a single memristor in high resistance state and in low resistance state can be used to generate two clearly distinguishable sets of second and higher harmonics. The power conversion efficiencies (PCEs) for higher harmonics generation can be derived from the normalized charge-flux curves of the single memristor [2]. The PCEs can be possibly used in neuromorphic computing. [1] G.Z. Cohen et al., Appl. Phys. Lett. 100, 133109 (2012) [2] N. Du et al., Rev. Sci. Instrum. 84, 023903 (2013)
