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…
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…
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…
Electronic structure and spin-orbit driven novel magnetism in d4.5 insulator Ba3YIr2O9
S. K. Panda, S. Bhowal, Ying Li +4
We have carried out a detailed first-principles study of a d quaternary iridate BaYIrO both in its 6H-perovskite-type ambient pressure (AP) phase and also for t…
Spin-orbital liquid state assisted by singlet-triplet excitation in ground state of BaZnIrO
Abhishek Nag, Srimanta Middey, Sayantika Bhowal +17
Strong spin-orbit coupling (SOC) effects of heavy -orbital elements have long been neglected in describing the ground states of their compounds thereby overlooking a variety of…
