Layer- and Field-Dependent Magnetic Order in 2D CrSBr Revealed by Pulsed Nanocalorimetry
Hugo Gomez-Torres, Roop K. Mech, Alessandra Canetta +9
Understanding the evolution of magnetic order in the two-dimensional limit remains a central challenge in van der Waals magnets, where thermodynamic measurements are constrained by…
Raman spectroscopy of van der Waals topological magnet GdGaI
Nan Jiang, Yijin Zhang, Yujie Xia +9
We report polarization-resolved Raman spectroscopy of a van der Waals compound GdGaI that is a candidate for excitonic insulators. By combining the symmetry analysis with density f…
Anomalous magneto-optical response at van der Waals interface
Muhammad Hassan Shaikh, Abhijith Puthiya Veettil, Collin Maurtua +9
Ruthenium dioxide () has been proposed as an altermagnetic candidate, although its magnetic ground state remains controversial. Here, we probe weak interfacial magn…
Layer-parity-defined surface polarization in NbCl for excitonic modulation at van der Waals interfaces
Xinyue Huang, Hansheng Xu, Yuchen Gao +10
The intrinsic symmetry breaking in the breathing kagome lattice of layered NbCl provides a unique mechanism for realizing electrically polar surfaces. In each monolayer, th…
Moire-Engineered Excitonic Landscape and Phonon-Mediated Recombination in Twisted WSe2 Bilayers
Memansa Thapa, Aksa Thomas, Jayalekshmi U. J. +7
We report light emission from the moire superlattice of a twisted bilayer of tungsten diselenide (WSe2/WSe2) encapsulated in insulating hexagonal boron nitride (hBN). The low-tempe…
Impact of Disorder Dynamics and Multi-Domain Kinetics on the Sliding Ferroelectricity of CVD-Grown 3R-WSe2 Bilayers
Sourav Paul, Prasenjit Ghosh, Krishna Prasad Maity +9
Sliding ferroelectricity in van der Waals (vdW) layered systems has emerged as a promising route toward non-volatile nanoscale devices, where interlayer displacement in non-centros…
