Tracking the evolution from isolated dimers to many-body entanglement in NaLu${}_x$Yb${}_{1-x}$Se${}_2$

Abstract

We synthesize homogeneous compositions of NaLu${}_x$Yb${}_{1-x}$Se${}_2$, connecting non-magnetic NaLuSe${}_2$ to the triangular lattice spin liquid candidate NaYbSe${}_2$. Thermal and magnetic properties are studied as the system evolves from one with dilute magnetic defects to one of a dense magnetic lattice. The field and temperature dependent heat capacity show the carriers of entropy crossover from isolated magnetic ions to a correlated lattice borne from spin dimers. For the dilute system we estimate the single ion anisotropy $(g_{\perp }/g_{\parallel }=3.13)$ and also the dimer exchange couplings $J_{\parallel }(=5.4$~K) and $J_{\perp }(=9.6$~K), in order to draw comparison to the half-doped and full magnetic compounds.
