A high-entropy form of MnSn with distinct magnetotransport regimes correlated to different magnetic structures
Kyle W. Fruhling, Jonathan Gaudet, William D. Ratcliff +9
The kagome MnSn material family has attracted significant attention as high-temperature metallic magnets with a host of different magnetic orderings and anisotropy. Theo…
Lanthanide Ion Electronic Structure Controls Magnetic Excitations in Topological Quantum Ferrimagnets (Ln = Tb, Dy, Ho)
Kelsey A. Collins, Jacob Pfund, Michael R. Page +3
The family of topological magnets is a promising platform for next-generation spintronic and magnonic technologies. However, the influence of the lanthanide ion ($…
Raman and Terahertz Spectroscopy of Low-Frequency Chiral Phonons in Amino Acids
Rahul Rao, Won Jin Choi, Joseph M. Slocik +6
Chiral phonons are mirror-symmetric vibrations that correspond to twisting and rotational motions of atoms. In chiral biomolecules, they correspond to low-energy terahertz (THz)-ra…
Highly Efficient Second/Third Harmonic Generation in van der Waals Layered Material AgScP2S6 with Anisotropic Polarization and Temperature Dependence
Mohamed Yaseen Noor, Ryan Siebenaller, Wenhao Liu +12
Single-crystal X-ray diffraction and nonlinear optical measurements, especially second- and third-harmonic generation (SHG/THG) are comprehensively investigated for the van der Waa…
Engineering the Magnetocaloric Effect in NdB
Kyle W. Fruhling, Enrique O. González Delgado, Siddharth Nandanwar +4
We present a comprehensive study of the magnetocaloric effect (MCE) in the NdB system where = Fe, Co, and Ni. These compounds are ferromagnetic kagome materials with tunab…
Observation of giant remnant polarization in ultrathin AlScN at cryogenic temperatures
Seunguk Song, Dhiren K. Pradhan, Zekun Hu +7
The discovery of wurtzite ferroelectrics opens new frontiers in polar materials, yet their behavior at cryogenic temperatures remains unexplored. Here, we reveal unprecedented ferr…
