Abstract

We present a study of Sm $_{3}$ Sb $_{3}$ Zn $_{2}$ O $_{14}$ (SSZO) through magnetization and specific heat capacity $C_{p} (T)$ measurements. SSZO contains well separated planes of Sm $^{3 +}$ magnetic ions on a Kagomé lattice. Though our magnetic susceptibility (where the data are limited down to 2\,K) does not show any anomaly, the $C_{p} (T)$ data which have been taken down to 0.35 K reveal a broad maximum at $T \sim 1.5$ \,K followed by a sharp peak at $T \sim 0.5$ \,K indicative of short-range correlations and long-range order, respectively.
