Physical properties of new delafossite triangular-lattice compounds TlErSe and TlTmSe
Bastian Rubrecht, Ellen Häußler, Mirtha Pillaca +7
Delafossite compounds containing rare-earth ions have been proven to be an ideal platform to investigate frustrated magnetic ground states. Here, we discuss two triangular-lattice…
More bridging ligands activate direct exchange: the case of anisotropic Kitaev effective magnetic interactions
Pritam Bhattacharyya, Nikolay A. Bogdanov, Liviu Hozoi
A magnet is a collection of magnetic moments. How those interact is determined by what lies in between. In transition-metal and rare-earth magnetic compounds, the configuration of…
Relevance of on-site and intersite Coulomb interactions in the Kitaev-Heisenberg magnet NaCoSbO
Pritam Bhattacharyya, Abdul Basit, Thorben Petersen +3
The detection of considerable spin frustration in honeycomb cobalt oxide compounds indicates the presence of sizable Kitaev interactions in these systems, enlarging the pool of Kit…
Distinct contiguous versus separated triplet-pair multiexcitons in an intramolecular singlet fission chromophore
R. Chesler, P. Bhattacharyya, A. Shukla +1
We show from many-body quantum mechanical calculations that there occur structurally distinct triplet-pair eigenstates in the intramolecular singlet fission (iSF) compound pentacen…
