Geometric frustration and Dzyaloshinskii-Moriya interactions in a quantum star lattice hybrid copper sulfate
Hajime Ishikawa, Yuto Ishii, Takeshi Yajima +6
We study the magnetism of a layered, spin- organic-inorganic copper sulfate, which is a close realization of the star lattice antiferromagnet, one of the playgrounds of ge…
Data-driven estimation of transfer integrals in undoped cuprates
Denys Y. Kononenko, Ulrich K. Rößler, Jeroen van den Brink +1
Undoped cuprates are an abundant class of magnetic insulators, in which the synergy of rich chemistry and sizable quantum fluctuations leads to a variety of magnetic behaviors. Und…
Evidence of The Anomalous Fluctuating Magnetic State by Pressure Driven 4f Valence Change in EuNiGe
K. Chen, C. Luo, Y. Zhao F. Baudelet +5
In rare-earth compounds with valence fluctuation, the proximity of the 4f level to the Fermi energy leads to instabilities of the charge configuration and the magnetic moment. Here…
Resonating holes vs molecular spin-orbit coupled states in group-5 lacunar spinels
Thorben Petersen, Pritam Bhattacharyya, Ulrich K. Rößler +1
The valence electronic structure of magnetic centers is one of the factors that determines the characteristics of a magnet. It may refer to orbital degeneracy, as for $j_\text{eff}…
Quantum chemical insights into hexaboride electronic structures: correlations within the boron -orbital subsystem
Thorben Petersen, Ulrich K. Rößler, Liviu Hozoi
The notion of strong electronic correlations arose in the context of -metal oxides such as NiO but can be exemplified on systems as simple as the H molecule. Here we shed li…
Surface and electronic structure at atomic length scales of the non-symmorphic antiferromagnet EuInSb
M. Victoria Ale Crivillero, Sahana Rößler, Priscila F. S. Rosa +3
We performed Scanning Tunneling Microscopy and Spectroscopy (STM/STS) measurements to investigate the Zintl phase EuInSb, a non-symmorphic antiferromagnet. The theoreti…
