✦ Synopsis

We found OeOuOa to be a heart fermlon compound Mth orthorhombic structure of UeOu~ type. In this report, we present the measurements of its resist~viW from 0.SK to 300K and of specific heat from 1.SK ~o 3OK.

The temperature dependence of resistiviw shows Kondo behavior below 30K. The specific heat abox~ IOK is well lit¢cd by. a sum of the electron contribution ~/T and the phonon contribution 3T ~, whereas the ratio C/T remarkabb" increase below 10K and is also well fitted by 7 + fl Tl with a huge 3 value 1.46J/K~.mol below
