Origin of the unconventional magnetoresistance in Sr2FeMoO6
Sugata Ray, Srimanta Middey, Somnath Jana +5
The unusual magnetoresistance (MR) behavior in Sr2FeMoO6, recently termed as spin-valve type MR (SVMR), presents several anomalies that are little understood so far. The difficulty…
Origin of Magnetism and trend in in Cr-based double perovskites: Interplay of two driving mechanisms
Hena Das, Prabuddha Sanyal, T. Saha-Dasgupta +1
Employing first principles density functional calculations, together with solution of the low-energy, model Hamiltonian constructed in a first principles manner, we explored the or…
Novel effects of localization due to `intrinsic disorder' in the `two-fluid' model for manganites
Prabuddha Sanyal, V. B. Shenoy, H. R. Krishnamurthy +1
We discuss the effects of a novel polaronic disorder in the recently proposed two-fluid model for manganites. Using effective field theory as well as direct numerical simulations,…
