Low frequency random telegraphic noise (RTN) and 1/f noise in the rare-earth manganite Pr${}_{0.63}$Ca${}_{0.37}$MnO${}_3$ near the charge-ordering transition

Aveek bid, Ayan Guha, A. K. Raychaudhuri

We have studied low frequency resistance fluctuations (noise) in a single crystal of the rare earth perovskite manganite Pr${}_{0.63}$Ca${}_{0.37}$MnO${}_3$ which shows a charge ordering…
