Abstract

Low temperature specific heat measurements on Y1-xPrxBa2Cu3O7 compounds with x=0.45, 0.6 in temperatures ranging from 0.1 to 30K, and resistance measurements with x=0.45, 0.5 for both polycrystalline and film sample in temperatures ranging from 4.2 to 100K are reported. The Kondo effect has been observed from both the specific heat and resistance mearements. The Te depression and metal-insulator transition in this system are attributed to localization due to the Kondo interaction of Pr 4f-electrons with hole carrier in CuO2 plane.
