Transport and Magnetic properties of laser ablated La0.7Ce0.3MnO3 films on LaAlO3: Effect of oxygen pressure, sample thickness and co-doping with Ca
P. Raychaudhuri, S. Mukherjee, A. K. Nigam +3
La0.7Ce0.3MnO3 is a relatively new addition in the family of colossal magnetoresistive manganites where the cerium ion is believed to be in the Ce4+ state. In this paper we report…

Critical behaviour in
S. Mukherjee, P. Raychaudhuri, A. K. Nigam
We have studied the critical behaviour in near the paramagnetic-ferromagnetic transition temperature. We have analysed our dc magnetisation data near the…

Magnetic field dependent variable range hopping behaviour in resistivity at low temperatures in polycrystalline colossal magnetoresistive manganites: evidence of spin polarised tunnelling
P. Raychaudhuri, P. Taneja, S. Sarkar +3
It has been observed that the low temperature magnetoresistance behaviour in polycrystalline colossal magnetoresistive (CMR) manganites differ significantly from the single crystal…
