Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe
Tao Xie, A. A. Eberharter, Jie Xing +14
Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly en…
Field-Induced Spin Excitations in the Spin-1/2 Triangular-Lattice Antiferromagnet CsYbSe
Tao Xie, Jie Xing, S. E. Nikitin +7
A layered triangular lattice with spin-1/2 ions is an ideal platform to explore highly entangled exotic states like quantum spin liquid (QSL). Here, we report a systematic in-field…
Crystal structure and phase transitions at high pressures in the superconductor FeSe0.89S0.11
