Between Mott and cluster Mott: spin-orbit entangled dimer singlets in BaCeRuO
L. Pätzold, A. Sandberg, H. Schilling +8
The hexagonal 4d ruthenates Ba3MRu2O9 host structural dimers and exhibit a delicate balance of competing interactions. Hund's coupling, trigonal crystal-field splitting, and hoppin…
Synthesis of epitaxial TaO thin films on AlO by suboxide molecular-beam epitaxy and thermal laser epitaxy
Yorick A. Birkhölzer, Anna S. Park, Noah Schnitzer +28
Tantalum dioxide (TaO2) is a metastable tantalum compound. Here, we report the epitaxial stabilization of TaO2 on Al2O3 (1-102) (r-plane sapphire) substrates using suboxide molecul…
Magnetic-field-induced critical dynamics in magnetoelectric TbPO
Christoph P. Grams, Markus Grüninger, Joachim Hemberger
We report on the magnetoelectric dynamics in the linear magnetoelectric antiferromagnet TbPO studied by broadband dielectric spectroscopy. For the phase transition into the mag…
Spin-orbit coupling in a half-filled shell: the case of KReCl
P. Warzanowski, M. Magnaterra, G. Schlicht +9
The half-filled shell of the configuration usually, in LS coupling, hosts a S = 3/2 ground state with quenched orbital moment. This state is not Jahn-Teller act…
Quasimolecular =3/2 moments in the cluster Mott insulator GaTaSe
M. Magnaterra, J. Attig, L. Peterlini +8
Quasimolecular orbitals in cluster Mott insulators provide a route to tailor exchange interactions, which may yield novel quantum phases of matter. We demonstrate the cluster Mott…
Terahertz measurements on subwavelength-size samples down to the tunneling limit
D. Maluski, I. Cámara Mayorga, J. Hemberger +1
For terahertz spectroscopy on single crystals, the wavelength often is comparable to the size of the studied samples, emphasizing diffraction effects. Using a continuous-wave t…
