Low frequency random telegraphic noise (RTN) and 1/f noise in the rare-earth manganite PrCaMnO 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 PrCaMnO which shows a charge ordering…
Specific heat study of single crystalline Pr Ca MnO in presence of a magnetic field
A. K. Raychaudhuri, Ayan Guha, I. Das +2
We present the results of a study of specific heat on a single crystal of PrCaMnO performed over a temperature range 3K-300K in presence of 0 and 8T magnetic…
Thermal relaxation in charge ordered Pr Ca MnO in presence of a magnetic field
A. K. Raychaudhuri, Ayan Guha, I. Das +2
We report observation of substantial thermal relaxation in single crystal of charge ordered system PrCaMnO in an applied magnetic field of H = 8T. The relaxat…
Magnetic Field resulting from non-linear electrical transport in single crystals of charge-ordered Pr Ca MnO}
Ayan Guha, N. Khare, A. K. Raychaudhuri +1
In this letter we report that the current induced destabilization of the charge ordered (CO) state in a rare-earth manganite gives rise to regions with ferromagnetic correlation. W…
Non-linear conduction in charge-ordered Pr Ca MnO : Effect of magnetic fields
Ayan Guha, A. K. Raychaudhuri, A. R. Raju +1
Non-linear conduction in a single crystal of charge-ordered PrCaMnO has been investigated in an applied magnetic field. In zero field, the non-linear conduc…
Non-linear electrical conduction and broadband noise in charge-ordered rare earth manganate Nd_0.5Ca_0.5MnO_3
Ayan Guha, Arindam Ghosh, A. K. Raychaudhuri +3
Measurements of the dc transport properties and the low-frequency conductivity noise in films of charge ordered Nd_0.5Ca_0.5MnO_3 grown on Si subtrate reveal the existence of a thr…
