Magneto-transport studies on (Pr1/3Sm2/3)2/3A1/3MnO3 (A = Ca, Sr and Ba) compounds
Saket Asthana, D. Bahadur, A. K. Nigam +1
Magnetic and transport properties of (Pr1/3Sm2/3)2/3A1/3MnO3 (A = Ca, Sr and Ba) compounds, prepared by the citrate gel route, have been investigated. These compounds are found to…
Valence electronic structure of Mn in undoped and doped lanthanum manganites from relative K x-ray intensity studies
S. Raj, H. C. Padhi, P. Rayachaudhury +5
Relative x-ray intensities of in , , and ( = , , and ) systems have been measured following excitation by…
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…
Metal-Insulator Transition and Ferromagnetism in the Electron Doped Layered Manganites La2.3-xYxCa0.7Mn2O7 (x=0,0.3,0.5)
P. Raychaudhuri, C. Mitra, A. Paramekanti +3
Bulk samples of La2.3-xYxCa0.7Mn2O7, x=0,0.3,0.5, with layered perovskite structure have been synthesized and investigated with respect to their electrical, electronic and magnetic…
A phenomenological model for magnetoresistance in granular polycrystalline colossal magnetoresistive materials: the role of spin polarised tunnelling at the grain boundaries
P. Raychaudhuri, T. K. Nath, A. K. Nigam +1
It has been observed that in bulk and polycrystalline thin films of collossal magnetoresistive (CMR) materials the magnetoresistance follows a different behaviour compared to singl…
