Colossal magnetostriction effect in rare-earth orthoferrites
Moumita Das, Arup Ghosh, Moumita Nandi +3
Within the entire gamut of magnetostrictive, piezomagnetic, and ferromagnetic shape memory alloy systems, the striction effect is found to vary from a few tens of parts per million…
Introducing antiferromagnetic ordering on the surface states of Bi2Se3 topological insulator by Europium doping
Sumana Paul, Moumita Das, Sujoy Datta +3
Topological insulators (TIs) are materials with an insulating bulk characterized by a gapped band structure, along with gapless metallic surface states having a Dirac cone with a h…
Quantum Zeno and anti-Zeno effects in the dynamics of non-degenerate hyper-Raman processes coupled to two linear waveguides
Moumita Das, Biswajit Sen, Kishore Thapliyal +1
The effect of the presence of two probe waveguides on the dynamics of hyper-Raman processes is studied in terms of quantum Zeno and anti-Zeno effects. Specifically, the enhancement…
Interplay between quantum Zeno and anti-Zeno effects in a non-degenerate hyper-Raman nonlinear optical coupler
Moumita Das, Kishore Thapliyal, Biswajit Sen +2
Quantum Zeno and anti-Zeno effects are studied in an asymmetric nonlinear optical coupler composed of a probe waveguide and a system waveguide. The system is a nonlinear waveguide…
Effect of hydrostatic pressure on ferromagnetism in two-dimensional CrI
Suchanda Mondal, Murugesan Kannan, Moumita Das +5
We have investigated the magnetic properties of highly anisotropic layered ferromagnetic semiconductor CrI in presence of hydrostatic pressure (). At ambient pressure, magne…
Giant magnetocaloric effect in exchange-frustrated GdCrTiO5 antiferromagnet
M. Das, S. Roy, N. Khan +1
We report the effect of exchange frustration on the magnetocaloric properties of GdCrTiO compound. Due to the highly exchange-frustrated nature of magnetic interaction, in GdCr…
