Tb3Ag4Sn4 has been studied using both bulk magnetization and Sn-119 Mossbauer spectroscopy. We find evidence for a first-order magnetostructural transition at 28 K, followed by a spin reorientation at 13 K. Three tin sites with hyperfine fields of 8.0, 4.2, and 3.5 T are observed at 2 K with area ratios of 2:1:1. Magnetization at 5 K is linear up to 9 T, indicating antiferromagnetic ordering.

Abstract
Tb3Ag4Sn4 has been studied using both bulk magnetization and Sn-119 Mossbauer spectroscopy. We find evidence for a first-order magnetostructural transition at 28 K, followed by a spin reorientation at 13 K. Three tin sites with hyperfine fields of 8.0, 4.2, and 3.5 T are observed at 2 K with area ratios of 2:1:1. Magnetization at 5 K is linear up to 9 T, indicating antiferromagnetic ordering.
