Magnetic order in the $S_{\mathrm{eff}}$ = 1/2 triangular-lattice compound NdCd${}_3$P${}_3$

Abstract

We present and characterize a new member of the $R$Cd${}_3$P${}_3$ ($R$= rare earth) family of materials, NdCd${}_3$P${}_3$, which possesses Nd${}^{3+}$ cations arranged on well-separated triangular lattice layers. Magnetic susceptibility and heat capacity measurements demonstrate a likely $S_{\mathrm{eff}}$ = 1/2 ground state, and also reveal the formation of long-range antiferromagnetic order at $T_N=0.34$ K. Via measurements of magnetization, heat capacity, and electrical resistivity, we characterize the electronic properties of NdCd${}_3$P${}_3$ and compare results to density functional theory calculations.
