Spin dynamics of a magnetic Weyl semimetal SrMnSb
Zhengwei Cai, Song Bao, Wei Wang +12
Dirac matters provide a platform for exploring the interplay of their carriers with other quantum phenomena. SrMnSb has been proposed to be a magnetic Weyl semi…
Patterns and driving forces of dimensionality-dependent charge density waves in 2H-type transition metal dichalcogenides
Dongjing Lin, Shichao Li, Jinsheng Wen +8
Two-dimensional (2D) materials have become a fertile playground for the exploration and manipulation of novel collective electronic states. Recent experiments have unveiled a varie…
Turning ZrTe5 into semiconductor through atomic intercalation
Qi-Yuan Li, Yang-Yang Lv, Jinghui Wang +11
In this work, we use the liquid ammonia method to successfully intercalate potassium atoms into ZrTe5 single crystal, and find a transition from semimetal to semiconductor at low t…
Evidence for a Dirac nodal-line semimetal in SrAs
Shichao Li, Zhaopeng Guo, Dongzhi Fu +11
Dirac nodal-line semimetals with the linear bands crossing along a line or loop, represent a new topological state of matter. Here, by carrying out magnetotransport measurements an…
Spin-wave induced phonon resonance in multiferroic BiFeO
Zhijun Xu, J. A. Schneeloch, Jinsheng Wen +13
We report the direct observation of a "resonance" mode in the lowest-energy optic phonon very near the zone center around (111) in the multiferroic BiFeO using neutron scatteri…
Fluctuating defects in the incipient relaxor KLiTaO (x=0.02)
C. Stock, P. M. Gehring, G. Xu +5
We report neutron scattering measurements of the structural correlations associated with the apparent relaxor transition in KLiTaO for (KLT(0.02)). This co…
The effect of local dipole moments on the structure and lattice dynamics of K0.98Li0.02TaO3
Jinsheng Wen, Guangyong Xu, C. Stock +5
We present high energy x-ray (67 keV) and neutron scattering measurements on a single crystal of KLiTaO for which the Li content () is less than $x_c = 0.02…
Response of polar nanoregions in 68%Pb(Mg1/3Nb2/3)O3-32%PbTiO3 to a [001] electric field
Jinsheng Wen, Guangyong Xu, C. Stock +1
We report neutron diffuse scattering measurements on a single crystal of 68%Pb(Mg1/3Nb2/3)O3-32%PbTiO3. Strong diffuse scattering is observed at low temperatures. An external field…
Large Bi-2212 single crystal growth by the floating-zone technique
J. S. Wen, Z. J. Xu, G. Y. Xu +3
Effects of the growth velocity on the crystal growth behavior of Bi_2Sr_2Ca_1Cu_2O_x (Bi-2212) have been studied by floating zone technique. The results show that a necessary condi…
Phase instability induced by polar nanoregions in a relaxor ferroelectric system
Guangyong Xu, Jinsheng Wen, C. Stock +1
Local inhomogeneities known as polar nanoregions (PNR) play a key role in governing the dielectric properties of relaxor ferroelectrics - a special class of material that exhibits…
