Effect of size reduction on the ferromagnetism of the manganite La1-xCaxMnO3 (x = 0.33)
Tapati Sarkar, A. K. Raychaudhuri, A. K. Bera +1
In this paper we report an investigation on the ferromagnetic state and the nature of ferromagnetic transition of nanoparticles of using magnetic…
Frequency dependence of dielectric anomaly around Neel temperature in bilayer manganite Pr(Sr0.1Ca0.9)2Mn2O7
Barnali Ghosh, Dipten Bhattacharya, A. K. Raychaudhuri +1
A novel frequency dependence of anomaly in dielectric constant versus temperature plot, around the Neel temperature T_N (~150 K), has been observed in a single crystal of bilayer m…
Hot electron effects and non-linear transport in hole doped manganites
Himanshu Jain, A. K. Raychaudhuri
We show that strong non--linear electron transport in the ferromagnetic insulating (FMI) state of manganites, responsible for phenomena such as colossal electroresistance and curre…
Size induced change-over from first to second order magnetic phase transition in La0.67Ca0.33MnO3 nanoparticles
Tapati Sarkar, A. K. Raychaudhuri
In this report we show that in the perovskite manganite La_{1-x}Ca_{x}MnO_3 for a fixed x \approx 0.33, the magnetic transition changes over from first order to second order on red…
Colossal electroresistance in ferromagnetic insulating state of single crystal NdPbMnO
Himanshu Jain, A. K. Raychaudhuri, Nilotpal Ghosh +1
Colossal electroresistance (CER) has been observed in the ferromagnetic insulating (FMI) state of a manganite. Notably, the CER in the FMI state occurs in the absence of magnetores…
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…
