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…
Pronounced 2/3 magnetization plateau in a frustrated = 1 isolated spin-triangle compound: Interplay between Heisenberg and biquadratic exchange interactions
S. Chattopadhyay, B. Lenz, S. Kanungo +13
We report the synthesis and characterization of a new quantum magnet [2-[Bis(2-hydroxybenzyl)aminomethyl]pyridine]Ni(II)-trimer (BHAP-Ni3) in single-crystalline form. Our combined…
The Dirac nodal line network in non-symmorphic rutile semimetal RuO
Vedran Jovic, Roland J. Koch, Swarup K. Panda +11
We employ angle resolved photoemission spectroscopy (ARPES) to investigate the Fermi surface of RuO. We find a network of two Dirac nodal lines (DNL) as previously predicted in…
Magnetic Order and Lattice Instabilities in NiMnSn Heusler based Magnetic Shape-Memory Alloys
Vijay Singh, Ambroise van Roekeghem, S. K. Panda +3
The magnetic correlations in the austenite phase and the consequent martensitic transition in inverse magnetocaloric alloys, NiMnSn, have been a matter of deb…
Rank of weighted digraphs with blocks
Ranveer Singh, Swarup Kumar Panda, Naomi Shaked-Monderer +1
Let be a digraph and be its rank. Many interesting results on the rank of an undirected graph appear in the literature, but not much information about the rank of a digr…
Pressure dependence of dynamically screened Coulomb interactions in NiO: Effective Hubbard, Hund, intershell and intersite components
S. K. Panda, H. Jiang, S. Biermann
In this work, we report the pressure dependence of the effective Coulomb interaction parameters (Hubbard U) in paramagnetic NiO within the constrained random phase approximation (c…
