Magnetic phase diagram and multiple field-induced states in the intermetallic triangular-lattice antiferromagnet NdAuAlGe with Ising-like spins
Mengru Cong, Han Ge, Lei Zhang +12
Geometrical frustration and the enhancement of strong quantum fluctuations in two-dimensional triangular antiferromagnets can lead to various intriguing phenomena. Here, we studied…
Optical conductivity and vibrational spectra of the narrow-gap semiconductor FeGa
C. Martin, V. A. Martinez, M. Opačić +11
Intermetallic narrow-gap semiconductors have been intensively explored due to their large thermoelectric power at low temperatures and a possible role of strong electronic correlat…
Ultrasensitive barocaloric material for room-temperature solid-state refrigeration
Qingyong Ren, Ji Qi, Dehong Yu +7
Solid-state refrigeration based on caloric effects is an energetically efficient and environmentally friendly technology, which is deemed as a potential alternative to the conventi…
Ultrafast ferromagnetic fluctuations preceding magnetoelastic first-order transitions
Zhao Zhang, Yanna Chen, Dehong Yu +18
First-order magnetic transitions are of both fundamental and technological interest given that a number of emergent phases and functionalities are thereby created. Of particular in…
Room-Temperature Skyrmion Thermopower in Fe3Sn2
Qianheng Du, Myung-Geun Han, Yu Liu +3
We present first room-temperature thermoelectric signature of the skyrmion lattice. This was observed in Fe3Sn2, a Kagome Dirac crystal with massive Dirac fermions that features hi…
Dimer rattling mode induced low thermal conductivity in an excellent acoustic conductor
Ji Qi, Baojuan Dong, Zhe Zhang +19
A solid with larger sound speeds exhibits higher lattice thermal conductivity (k_{lat}). Diamond is a prominent instance where its mean sound speed is 14400 m s-1 and k_{lat} is 23…
Magnetic-field control of topological electronic response near room temperature in correlated Kagome magnets
Yangmu Li, Qi Wang, Lisa DeBeer-Schmitt +13
Strongly correlated Kagome magnets are promising candidates for achieving controllable topological devices owing to the rich interplay between inherent Dirac fermions and correlati…
Colossal barocaloric effects in plastic crystals
Bing Li, Yukinobu Kawakita, Hui Wang +6
Solid-state refrigeration technology based on caloric effects are promising to replace the currently used vapor compression cycles. However, their application is restricted due to…
Absence of Dirac states in BaZnBi induced by spin-orbit coupling
Weijun Ren, Aifeng Wang, D. Graf +4
We report magnetotransport properties of BaZnBi single crystals. Whereas electronic structure features Dirac states, such states are removed from the Fermi level by spin-orbi…
