Possible signature of broken symmetry state near the quantum critical point in P doped BaFeAs: A Raman spectroscopy study
Debasmita Swain, Soumyadeep Ghosh, K. Bera +4
We study the iron-pnictide compound BaFe(AsP) for x 0.23, with a doping concentration near quantum criticality and enhanced nematic fluctuating state in t…
Magnetic anisotropy of the alkali iridate NaIrO at high magnetic fields: evidence for strong ferromagnetic Kitaev correlations
Sitikantha. D Das, Sarbajaya Kundu, Zengwei Zhu +10
The magnetic field response of the Mott-insulating honeycomb iridate NaIrO is investigated using torque magnetometry measurements in magnetic fields up to 60 tesla. A p…
Quantum Criticality in the 122 Iron Pnictide Superconductors Emerging from Orbital-Selective Mottness
S. D. Das, M. S. Laad, L. Craco +3
The twin issues of the nature of the normal state and competing order(s) in the iron arsenides are central to understanding their unconventional, high-Tc superconductivity. We use…
Isothermal magnetic entropy behavior in Tb5Si3: Sign reversal and non-monotonic variation with temperature, and implications
Niharika Mohapatraa, Sitikantha D. Das, K. Mukherjee +1
The magnetic entropy change (\DeltaS), a measure of the magnetocaloric effect, in Tb5Si3, a compound exhibiting unusual positive magnetoresistance following a magnetic-field-induce…
Magnetism of fine particles of Kondo lattices, obtained by high-energy ball-milling
E. V. Sampathkumaran, K. Mukherjee, Kartik K Iyer +2
Despite intense research in the field of strongly correlated electron behavior for the past few decades, there has been very little effort to understand this phenomenon in nano par…
An anomalous butterfly-shaped magnetoresistance loop in an alloy, Tb4LuSi3
K. Mukherjee, Sitikantha D Das, Niharika Mohapatra +2
Magnetic-field (H) induced first-order magnetic transition and the assiciated electronic phase-separation phenomena are active topics of research in magnetism. Magnetoresistance (M…
