Crossover from injection to tunneling conduction mode and associated magneto-resistance in a single (111)//Co spin-valve device
P. Dey, R. Rawat, S. R. Potdar +2
We demonstrate interface energy level engineering, exploiting the modification in energy band structure across Verwey phase transition of electrode, in a $Fe_{3}O_{4}…
Enhanced grain surface effect on magnetic properties of nanometric La0.7Ca0.3MnO3 manganite : Evidence of surface spin freezing of manganite nanoparticles
P. Dey, T. K. Nath, P. K. Manna +1
We have investigated the effect of nanometric grain size on magnetic properties of single phase, nanocrystalline, granular La0.7Ca0.3MnO3 (LCMO) sample. We have considered core-she…
Effect of substrate-induced strain on transport and magnetic properties of epitaxial La_0.66Sr_0.33MnO_3 thin films
Puja Dey, T. K. Nath, A. Taraphder
We have studied electrical transport and magnetic properties of epitaxial La_0.66 Sr_0.33 Mn O_3 thin films grown on different substrates having different lattice strains induced b…
Direct evidence of random field effect on magnetic ordering of La_(0.5)Gd_(0.2)Sr_(0.3)MnO_(3) manganite system
P. Dey, T. K. Nath, A. Banerjee
We report direct experimental evidence of the effect of quenched random field on magnetic ordering of La_(0.5)Gd_(0.2)Sr_(0.3)MnO_(3) manganites system. We demonstrate magnetic mea…
