Spin Dynamics in van der Waals Magnetic Systems
Chunli Tang, Laith Alahmed, Muntasir Mahdi +11
The discovery of atomic monolayer magnetic materials has stimulated intense research activities in the two-dimensional (2D) van der Waals (vdW) materials community. The field is gr…
Structural Monoclinicity and Its Coupling to Layered Magnetism in Few-Layer
Xiaoyu Guo, Wencan Jin, Zhipeng Ye +13
Using polarization-resolved Raman spectroscopy, we investigate layer number, temperature, and magnetic field dependence of Raman spectra in one- to four-layer . L…
Magnetism and Spin Dynamics in Room-Temperature van der Waals Magnet FeGeTe
Laith Alahmed, Bhuwan Nepal, Juan Macy +12
Two-dimensional (2D) van der Waals (vdWs) materials have gathered a lot of attention recently. However, the majority of these materials have Curie temperatures that are well below…
Tunable layered-magnetism-assisted magneto-Raman effect in a two-dimensional magnet
Wencan Jin, Zhipeng Ye, Xiangpeng Luo +13
We use a combination of polarized Raman spectroscopy experiment and model magnetism-phonon coupling calculations to study the rich magneto-Raman effect in the two-dimensional (2D)…
Second-order nonlinear optical and linear UV-VIS absorption properties of type-II multiferroic candidates RbFe(AO4)2 (A = Mo, Se, S)
Rachel Owen, Elizabeth Drueke, Charlotte Albunio +7
Motivated by the search for type-II multiferroics, we present a comprehensive optical study of a complex oxide family of type-II multiferroic candidates: RbFe(MoO4)2, RbFe(SeO4)2,…
Symmetry-resolved two-magnon excitations in a strong spin-orbit-coupled bilayer antiferromagnet
Siwen Li, Elizabeth Drueke, Zach Porter +7
We used a combination of polarized Raman spectroscopy and spin wave calculations to study magnetic excitations in the strong spin-orbit-coupled (SOC) bilayer perovskite antiferroma…
Correlating surface stoichiometry and termination in SrTiO films grown by hybrid molecular beam epitaxy
Suresh Thapa, Sydney R. Provence, Devin Jessup +6
Hybrid oxide molecular beam epitaxy (hMBE), a thin-film deposition technique in which transition metal cations are delivered using a metal-organic precursor, has emerged as the sta…
Observation of the polaronic character of excitons in a two-dimensional semiconducting magnet
Wencan Jin, Hyun Ho Kim, Zhipeng Ye +15
Exciton dynamics can be strongly affected by lattice vibrations through electron-phonon coupling. This is rarely explored in two-dimensional magnetic semiconductors. Focusing on bi…
Observation of a ferro-rotational order coupled with second-order nonlinear optical fields
Wencan Jin, Elizabeth Drueke, Siwen Li +6
The ferro-rotational order, whose order parameter (OP) is an axial vector invariant under both time reversal (TR) and spatial inversion (SI) operations, is the last remaining categ…
Polarized Raman spectroscopy study of metallic : a consistent picture of disorder-interrupted unidirectional charge order
Wencan Jin, Siwen Li, Jianpeng Liu +9
We have used rotational anisotropic polarized Raman spectroscopy to study the symmetries, the temperature and the doping dependence of the charge ordered state in metallic $(Sr_{1-…
Raman fingerprint of two terahertz spin wave branches in a two-dimensional honeycomb Ising ferromagnet
Wencan Jin, Hyun Ho Kim, Zhipeng Ye +13
Two-dimensional (2D) magnetism has been long sought-after and only very recently realized in atomic crystals of magnetic van der Waals materials. So far, a comprehensive understand…
Surface buckling of phosphorene materials: determination, origin and influence on electronic structure
