Description

We report here the magnetic susceptibility, specific heat and electrical resistivity on high-quality single crystals of YbIr2Si2. It crystallizes either in the I-type body-centered ThCr2Si2 or P-type CaBe2Ge2 structure. P-type sample orders magnetically below 0.7 K whereas the I-type system remains paramagnetic down to 40 mK and shows heavy fermion behavior. Low-temperature resistivity and specific heat of this compound has strong similarity with YbRh2Si2 down to 400 mK. However, below 200 mK YbIr2Si2 attains Fermi-liquid ground state in contrast to YbRh2Si2 which shows non-Fermi-liquid behavior
