要旨:
We present a study of Sm3Sb3Zn2O14 (SSZO) through magnetization and specific heat capacity Cp(T) measurements. SSZO contains well separated planes of Sm3+ magnetic ions on a Kagomé lattice. Though our magnetic susceptibility (where the data are limited down to 2K) does not show any anomaly, the Cp(T) data which have been taken down to 0.35 K reveal a broad maximum at T∼1.5 K followed by a sharp peak at T∼0.5 K indicative of short-range correlations and long-range order, respectively.
