“…We observe a clear Kondo behaviour in the thermal conductivity of TmGa 3 , similarly as we previously found such a behaviour in the case of TmIn 3 [11]. TmGa 3 undergoes two first-order transitions very close to each other at T N Z4.26 K and T Q Z 4.29 K, corresponding to antiferromagnetic and quadrupolar orderings [12]. The magnetic resistivity r m of TmGa 3 , taken as the difference between the resistivities of TmGa 3 and LuGa 3 , exhibits a clear log T behavior between 50 and 250 K [13].…”
