The cradle of quantum spin liquids, triangular antiferromagnets show strong proclivity to
magnetic order and require deliberate tuning to stabilize a spin-liquid state. In this brief …

High-quality single crystals of NaYbSe 2, which resembles a perfect triangular-lattice
antiferromagnet without intrinsic disorder, are investigated by magnetization and specific …

Triangular lattice of rare-earth ions with interacting effective spin-1/2 local moments is an
ideal platform to explore the physics of quantum spin liquids (QSLs) in the presence of …

A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL
candidate affects its true magnetic ground state. The ultimate question is whether the QSL …

An interplay of geometrical frustration and strong quantum fluctuations in a spin-1/2
triangular-lattice antiferromagnet (TAF) can lead to exotic quantum states. Here, we report …

Spectral probes, such as neutron scattering, are crucial for characterizing excitations in
quantum many-body systems and the properties of quantum materials. Among the most …

The most fascinating feature of certain two-dimensional (2D) gapless quantum spin liquid
(QSL) is that their spinon excitations behave like the fermionic carriers of a paramagnetic …

Here we present a neutron scattering-based study of magnetic excitations and magnetic
order in NaYbO 2 under the application of an external magnetic field. The crystalline electric …

By employing inelastic neutron scattering (INS) and Raman scattering (RS) experiments, we
comprehensively investigate crystalline electric field (CEF) excitations in NaYbSe 2, a new …

While the Heisenberg model for magnetic Mott insulators on planar lattice structures is
comparatively well understood in the case of transition metal ions, the intrinsic spin-orbit …
