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…
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…
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…
Impact of Rare-earth site Substitution on the Structural, Magnetic and Thermal Properties of CeEuCrO Orthochromite Solid-solutions
M. Taheri, F. S. Razavi, Z. Yamani +4
The role of slight changes of the chemical composition on antiferromagnetic ordering of Cr in rare-earth orthochoromites was investigated on a series of ceramic solid-solutions Ce$…
Linarite - a quasi-critical J-J chain
Eron Cemal, Mechthild Enderle, Reinhard K. Kremer +5
The mineral linarite, PbCuSO(OH), is a spin 1/2 chain with frustrating nearest neighbor ferromagnetic and next-nearest neighbor antiferromagnetic exchange interactions. Our…
