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 ($…
Non-local low energy neutral excitations in a strongly disordered triangular Mott magnet CrSeBr
Wenhao Liu, Dechen Zhang, Yuanqi Lyu +13
Understanding if low-energy excitations can remain itinerant in the presence of strong disorder remains a central challenge in frustrated quantum magnets, where disorder is general…
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…
Magnetism and magnetoelastic effect in 2D van der Waals multiferroic CuCrP2S6
Jiasen Guo, Ryan P. Siebenaller, Michael A. Susner +3
We report a magnetic and neutron diffraction study on the ground state magnetism and field evolution of single crystal van der Waals multiferroic CuCrP2S6. The ordered moments alig…
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…
