Mechanism for the high Neel temperature in SrTcO_3
S. Middey, Ashis Kumar Nandy, Priya Mahadevan +1
The microscopic origin of the high Neel temperature (T_N) observed experimentally in SrTcO_3 has been examined using a combination of ab-initio electronic structure calculations an…
Glass-like ordering and spatial inhomogeneity of magnetic structure in Ba3FeRu2O9 : The role of Fe/Ru-site disorder
Srimanta Middey, Sugata Ray, K. Mukherjee +7
Several doped 6H hexagonal ruthenates, having the general formula Ba3MRu2O9, have been studied over a significant period of time in order to understand the unusual magnetism of rut…
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…
Re-entrant ordering of solute in a colloidal suspension during solvent evaporation
Sumanta Mukherjee, Arnab Saha, Pralay K. Santra +2
We study the phenomenon of self-assembly of silica micro-spheres on a glass plate during evaporation of the solvent from a colloidal suspension. Our experiments unveil an interesti…
Relative stability of zincblende and wurtzite structure in CdX(X = S, Se, Te) series - A NMTO study
Soumendu Datta, Tanusri Saha-Dasgupta, D. D. Sarma
Using NMTO-downfolding technique we have revisited the issue of relative stability between zincblende (ZB) and wurtzite (WZ) symmetries in case of CdS, CdSe and CdTe semiconductors…
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…
