Electrical and Magnetic Properties of New Yb-Based Compound YbPd5Al2

We succeeded in growing a single crystal of YbPd 5 Al 2 with the tetragonal structure. The temperature dependence of electrical resistivity and a small value of the coefficient A in the Fermi liquid relation ρ=ρ 0 + A T 2 suggest that the 4 f -electrons are well localized. A magnetic ordering was found at T o =0.19 K in the specific heat measurement. On the other hand, the magnetic entropy exhibits only 0.5 R ln 2 at T o , and the specific heat shows a long tail above T o .
