Magnetic transition in the Jeff=1/2 Kagomé system Sm3Sb3Zn2O14

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...

Description
Summary: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∼1.5K followed by a sharp peak at T∼0.5K indicative of short-range correlations and long-range order, respectively. •Sm3Sb3Zn2O14 is explored by XRD, magnetization and heat capacity.•In SSZO, Sm3+ and Sb5+ ions form Kagomé layers where Sm3+ is magnetic.•Spin–orbit coupling and crystal-electric field are of comparable strength in SSZO.•Magnetization show small antiferromagnetic interactions among magnetic ions.•Heat capacity show short-range ordering at T∼1.5 K due to intra-Kagomé interactions.•Heat capacity show long-range ordering at T∼0.5 K due to inter-Kagomé interactions.
