Anisotropic field-induced ordering in the triangular-lattice quantum spin liquid NaYbSe 2

High-quality single crystals of ${\mathrm{NaYbSe}}_{2}$, which resembles a perfect triangular-lattice antiferromagnet without intrinsic disorder, are investigated by magnetization and specific heat, as well as the local probe techniques nuclear magnetic resonance (NMR) and electron spin resonance.
