Interplay of Orbital Degeneracy and Vacancies in Stabilizing Collinear Magnetic Order in CrTe
Prasanta Chowdhury, Jyotirmoy Sau, Mohamad Numan +7
CrTe, a two-dimensional van der Waals ferromagnet, displays a contested magnetic structure, poised between collinear and non-collinear spin configurations. In this work…
Magnetization, dielectric and thermal studies in the double perovskite polycrystalline compound Tm2CoMnO6
A. Banerjee, Gangadhar Das, V. Rajaji +2
We report here a comprehensive study on structural, magnetic, caloric and electronic properties of the monoclinic phase of double perovskite compound Tm2CoMnO6 (TCMO) in its polycr…
Evidence of exchange-striction and charge disproportionation in the magneto-electric material Ni3TeO6
Mohamad Numan, Gangadhar Das, Md Salman Khan +5
The chiral magneto-electric compound Ni3TeO6 is investigated through temperature-dependent synchrotron-based powder x-ray diffraction and x-ray absorption spectroscopy between 15 t…
Spin liquid behavior of a three-dimensional magnetic system BaNiIrO with = 1
Siddharth Kumar, S. K. Panda, Manju Mishra Patidar +7
The quantum spin liquid (QSL) is an exotic phase of magnetic materials where the spins continue to fluctuate without any symmetry breaking down to zero temperature. Among the handf…
Importance of site occupancy and absence of strain glassy phase in NiFeMnIn
R. Nevgi, Gangadhar Das, M. Acet +1
Martensitic transition temperature steadily decreases in NiFeMnIn and is completely suppressed at = 0.2. Despite suppression of martensitic transi…
Depth resolved chemical speciation of a superlattice structure
Gangadhar Das, A. G. Karydas, Haranath Ghosh +4
We report results of simultaneous x-ray reflectivity and grazing incidence x-ray fluorescence measurements in combination with x-ray standing wave assisted depth resolved near edge…
Determination of Surface Morphology of TiO2 nanostructure using synchrotron X-ray standing wave technique
Gangadhar Das, Manoj Kumar, A. K. Biswas +3
Nanostructures of Titanium oxide (TiO2) are being studied for many promising applications, e.g., solar photovoltaics, solar water splitting for H2 fuel generation etc., due to thei…
Structural and electronic properties of Fe(AlxGa1-x)3 system
Debashis Mondal, C. Kamal, Soma Banik +6
FeGa3 is a well known d-p hybridization induced intermetallic bandgap semiconductor. In this work, we present the experimental and theoretical results on the effect of Al substitut…
Temporal Coherence in Surface x-ray Standing Waves
M K Tiwari, Gangadhar Das
We present a unified elucidation for the role temporal coherence properties of x-rays in surface x-ray standing wave analysis, under total external reflection condition. Analytical…
Effect of Synchrotron Polarization in Grazing Incidence X-ray Fluorescence analysis
Gangadhar Das, M K Tiwari, A K Singh +1
Total reflection x-ray fluorescence (TXRF) spectroscopy has seen a remarkable progress over the past years. Numerous applications in basic and applied sciences prove its importance…
