Candidate Quantum Spin Liquid in the Ce\textsuperscript{3+} Pyrochlore Stannate Ce$_2$Sn$_2$O$_7$

We report the low temperature magnetic properties of Ce $_{2}$ Sn $_{2}$ O $_{7}$ , a rare-earth pyrochlore. Our susceptibility and magnetization measurements show that due to the thermal isolation of a Kramers doublet ground state, Ce $_{2}$ Sn $_{2}$ O $_{7}$ has Ising-like magnetic moments of $\sim 1.18$ $μ_{B}$ . The magnetic moments are confined to the local trigonal axes, as in a spin ice, but the exchange interactions are antiferromagnetic. Below 1 K the system enters a regime with antiferromagnetic correlations. In contrast to predictions for classical $⟨ 111 ⟩$ -Ising spins on the pyrochlore lattice, there is no sign of long-range ordering down to 0.02 K. Our results suggest that Ce $_{2}$ Sn $_{2}$ O $_{7}$ features an antiferromagnetic liquid ground state with strong quantum fluctuations.
