Element-Specific Visualization of Layer-Parity and Twist-Dependent Magnetism in CrSBr
Aalok Tiwari, Shubhada Patil, Ravi Kumar Bandapelli +16
Van der Waals (vdW) based antiferromagnets (AFMs) are an ideal platform for probing and understanding thickness- and twist-angle-dependent emergent spin phenomena. However, element…
Imaging of van der Waals Materials via Standing-Wave Photoemission Microscopy: Depth-Resolved Electronic Structure of WS2
J. R. Paudel, R. Muzzio, M. E. Matzelle +13
Two-dimensional van der Waals materials promise electronic, optoelectronic, and quantum technologies, yet depth-resolved characterization remains challenging. Here, we demonstrate…
Enabling Electrical Readout of Néel vector reversal in a van der Waals Antiferromagnet
Raghvendra Posti, Ravi Kumar Bandepalli, Wenhao Liu +14
Owing to its robustness against external perturbations and intrinsically ultrafast dynamics, the Néel vector in antiferromagnets (AFMs) can enable the development of next-generati…
Visualization of Tunable Electronic Structure of Monolayer TaIrTe
Sandy Adhitia Ekahana, Aalok Tiwari, Souvik Sasmal +16
Monolayer TaIrTe has emerged as an attractive material platform to study intriguing phenomena related to topology and strong electron correlations. Recently, strong interaction…
Temperature and Pressure Dependent Vibrational Properties of Pristine and Doped Vacancy-Ordered Double Perovskite
Aalok Tiwari, Karamjyoti Panigrahi, Mrinmay Sahu +2
Understanding lattice dynamics and structural transitions in vacancy-ordered double perovskites is crucial for developing lead-free optoelectronic materials, yet the role of dopant…
Magnetization Dependent In-plane Anomalous Hall Effect in a Low-dimensional System
I-Hsuan Kao, Ravi Kumar Bandapelli, Zhenhong Cui +17
Anomalous Hall Effect (AHE) response in magnetic systems is typically proportional to an out-of-plane magnetization component because of the restriction imposed by system symmetrie…
