The equiatomic stannide URhSn becomes ferromagnetic at 17.0(5) K. Its
investigation by both electrical resistivity and specific heat measure
ments reveals the existence of a second transition around 58 K: the re
sistivity decreases sharply acid the specific heat exhibits a great ju
mp (Delta C congruent to 10 J/K mel) at this temperature. Above 17 K,
any structural or magnetic transition can be detected by neutron diffr
action study.
