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…
Topotactic transformation of single-crystals: from perovskite to infinite-layer nickelates
Pascal Puphal, Yu-Mi Wu, Katrin Fürsich +9
Topotactic transformations between related crystal structures are a powerful emerging route for the synthesis of novel quantum materials. Whereas most such "soft chemistry" experim…
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…
Revealing three-dimensional quantum criticality by Sr-substitution in Han Purple
Stephan Allenspach, Pascal Puphal, Joosep Link +20
Classical and quantum phase transitions (QPTs), with their accompanying concepts of criticality and universality, are a cornerstone of statistical thermodynamics. An exemplary cont…
