Giant pressure-enhancement of multiferroicity in CuBr2
J. S. Zhang, Yiqi Xie, X. Q. Liu +16
Type-II multiferroic materials, in which ferroelectric polarization is induced by inversion non-symmetric magnetic order, promise new and highly efficient multifunctional applicati…
Barkhausen effect in the first order structural phase transition in type-II Weyl semimetal MoTe2
Chuanwu Cao, Xin Liu, Xiao Ren +7
We report the first observation of the non-magnetic Barkhausen effect in van der Waals layered crystals, specifically, between the Td and 1T' phases in type-II Weyl semimetal MoTe2…
Raman scattering study of tetragonal magnetic phase in SrNaFeAs: structural symmetry and electronic gap
Li Yue, Xiao Ren, Tingting Han +4
We use inelastic light scattering to study SrNaFeAs (), which exhibits a robust tetragonal magnetic phase that restores the four-fold rotation sym…
Spin-wave excitations evidencing the Kitaev interaction in single crystalline -RuCl
Kejing Ran, Jinghui Wang, Wei Wang +13
Kitaev interactions underlying a quantum spin liquid have been long sought, but experimental data from which their strengths can be determined directly is still lacking. Here, by c…
Raman signatures of inversion symmetry breaking and structural phase transition in type-II Weyl semimetal MoTe2
Kenan Zhang, Changhua Bao, Qiangqiang Gu +7
Transition metal dichalcogenide MoTe is an important candidate for realizing the newly predicted type-IIWeyl fermions, for which the breaking of the inversion symmetry is a pre…
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…
