Abstract
We have measured the specific heat C of single-crystalline YbPtSn as well as of polycrystalline non-magnetic LuPtSn in a wide temperature range between 1.2 and 300 K. At low temperatures, we found an obvious peak in C at 3.3 K due to an antiferromagnetic transition and three anomalous humps at 2.4, 2.1 and 1.9 K, respectively. The magnetic entropy achieves almost R ln 2 just above 3.3 K, which reveals that the ground state of YbPtSn is the Kramers doublet. The magnetic contribution to C shows a Shottky-type anomaly peaked around 110 K, suggesting that the first excited doublet exists at ∼270 K above the ground state. YbPtSn cannot be categorized as a heavy electron compound because of a small value of the electronic specific-heat coefficient.
