High-spin orbital interactions across van der Waals gaps controlling the interlayer ferromagnetism in van der Waals ferromagnets
Hyun-Joo Koo, Reinhard K. Kremer, Myung-Hwan Whangbo
We examined what interactions control the sign and strength of the interlayer coupling in van der Waals ferromagnets such as Fe3-xGeTe2, Cr2Ge2Te6, CrI3 and VI3, to find that high-…
Magnetic correlations in infinite-layer nickelates: an experimental and theoretical multi-method study
R. A. Ortiz, P. Puphal, M. Klett +12
We report a comprehensive study of magnetic correlations in LaNiO, a parent compound of the recently discovered family of infinite-layer (IL) nickelate superconductors, using…
Discovery of Superconductivity in (Ba,K)SbO
Minu Kim, Graham M. McNally, Hun-Ho Kim +12
Superconducting bismuthates (Ba,K)BiO (BKBO) constitute an interesting class of superconductors in that superconductivity with a remarkably high of 30 K arises…
Absence of Spin Frustration in the Kagomé Layers of Cu2+ Ions in Volborthite Cu3V2O7(OH)2x2H2O and Observation of the Suppression and Re-entrance of Specific Heat Anomalies in Volborthite Under External Magnetic Field
Myung-Hwan Whangboa, Hyun-Joo Koo, Eva Brücher +2
We determined the spin exchanges between the Cu2+ ions in the kagome layers of volborthite, Cu3V2O7(OH)2x2H2O, by performing the energy-mapping analysis based on DFT+U calculations…
Phase separation and pairing fluctuations in oxide materials
A. Bill, V. Hizhnyakov, R. K. Kremer +3
We investigate the microscopic mechanism of charge instabilities and the formation of inhomogeneous states in systems with strong electron correlations. It is demonstrated that wit…
Magnetoelastic study on the frustrated quasi-one-dimensional spin-1/2 magnet LiCuVO
A. Miyata, T. Hikihara, S. Furukawa +3
We investigated the magnetoelastic properties of the quasi-one-dimensional spin-1/2 frustrated magnet LiCuVO. Longitudinal-magnetostriction experiments were performed at 1.5 K…
