Spin-orbit entangled moments and magnetic exchange interactions in cobalt-based honeycomb magnets BaCo(O) ( = P, As, Sb)
Subhasis Samanta, Fabrizio Cossu, Heung-Sik Kim
Co-based honeycomb magnets have been actively studied recently for the potential realization of emergent quantum magnetism therein such as the Kitaev spin liquid. Here we employ de…
Suppression of Antiferromagnetic Order by Strain in Honeycomb Cobaltate: Implication for Quantum Spin Liquid
Gye-Hyeon Kim, Miju Park, Uksam Choi +8
Recently, layered honeycomb cobaltates have been predicted as a new promising system for realizing the Kitaev quantum spin liquid, a many-body quantum entangled ground state charac…
Optical detection of bond-dependent and frustrated spin in the two-dimensional cobalt-based honeycomb antiferromagnet Cu3Co2SbO6
Baekjune Kang, Uksam Choi, Taek Sun Jung +18
Two-dimensional honeycomb antiferromagnet becomes an important class of materials as it can provide a route to Kitaev quantum spin liquid, characterized by massive quantum entangle…
Emergence of flat bands and ferromagnetic fluctuations via orbital-selective electron correlations in Mn-based kagome metal
Subhasis Samanta, Hwiwoo Park, Chanhyeon Lee +6
Kagome lattice has been actively studied for the possible realization of frustration-induced two-dimensional flat bands and a number of correlation-induced phases. Currently, the s…
Effect of Frustrated Exchange Interactions and Spin-half Impurity on the Electronic Structure of Strongly Correlated NiFeO
Kodam Ugendar, S. Samanta, Sudhendra Rayaprol +3
Spin-polarized density functional calculations, magnetization, and neutron diffraction measurements are carried out to investigate the magnetic exchange interactions and strong cor…
