Self Injection length in La0.7 Ca0.3 Mno3-YBa 2Cu3O7-d ferromagnet- superconductor multi layer thin films
S. P. Pai, S. Wanchoo, S. C. Purandare +4
We have carried out extensive studies on the self-injection problem in barrierless heterojunctions between La0.7Ca0.3MnO3 (LCMO) and YBa2Cu3O7-d (YBCO). The heterojunctions were gr…
A 'p-n' diode with hole and electron-doped lanthanum manganite
C. Mitra, P. Raychaudhuri, G. Kobernik +4
The hole-doped manganite La0.7Ca0.3MnO3 and the electron-doped manganite La0.7Ce0.3MnO3 undergo an insulator to metal transition at around 250 K, above which both behave as a polar…
Peak effect in a superconducting DyBa2Cu3O7-y film at microwave frequencies
A. R. Bhangale, P. Raychaudhuri, S. Sarkar +4
We report the observation of a peak in the microwave (9.55 GHz) surface resistance in an epitaxial DyBa2Cu3O7-y superconducting film in magnetic fields (parallel to the c axis) ran…
Peak effect in laser ablated DyBa2Cu3O7-d films at microwave frequencies at subcritical currents
A. R. Bhangale, P. Raychaudhuri, T. Banerjee +2
In this paper we report the observation of a peak in the microwave surface resistance (at frequencies ~10GHz) of laser ablated DyBa2Cu3O7-d films in magnetic field ranging from 2 t…
Interesting history effect in the magnetotransport properies of La0.55Ho0.15Sr0.3MnOz films on LaAlO3
P Raychaudhuri, A E P de Araujo, F L A Machado +2
We report the magnetoresistance measurements of a highly oriented La0.55Ho0.15Sr0.3MnOz film on LaAlO3 substrate. The film has a metal-insulator transition around 200 K and shows p…
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…
