Observation of Unusual Magnetoelastic Effects in a Quasi-1D Spiral Magnet
Chong Wang, Daiwei Yu, Xiaoqiang Liu +10
We present a systematic study of spin and lattice dynamics in the quasi-one-dimensional spiral magnet CuBr2, using Raman scattering in conjunction with infrared and neutron spectro…
Nematic magnetoelastic effect contrasted between Ba(FeCo)As and FeSe
Yuwen Hu, Xiao Ren, Rui Zhang +8
To elucidate the origin of nematic order in Fe-based superconductors, we report a Raman scattering study of lattice dynamics, which quantify the extent of -symmetry breaking,…
Nematic crossover in BaFeAs under uniaxial stress
Xiao Ren, Lian Duan, Yuwen Hu +5
Raman scattering can detect spontaneous point-group symmetry breaking without resorting to single-domain samples. Here we use this technique to study , the par…
Charge density waves and phonon-electron coupling in ZrTe investigated by Raman spectroscopy and first-principles calculations
Yuwen Hu, Feipeng Zheng, Xiao Ren +2
Charge-density-wave (CDW) order has long been interpreted as arising from a Fermi-surface instability in the parent metallic phase. While phonon-electron coupling has been suggeste…
Identification and mechanical control of ferroelastic domain structure in rhombohedral CaMnO
Renliang Yuan, Lian Duan, Xinyu Du +1
We report on observation of ferroelastic domain structure in single crystals of multiferroic CaMnO at room temperature. Two types of ferroelastic domain wall are found,…
