EuNi2P2 is known as a heavy fermion compound with an electronic specific heat coefficient γ = 100 mJ/(K2·mol) . We grew single crystals and studied their electronic and magnetic properties by measuring the electrical resistivity, magnetic susceptibility, high-field magnetization, specific heat, and thermal expansion. The present heavy fermion state is clarified to be based on the Kondo effect as in CeRu2Si2, revealing an intensive shrinkage of the volume below about 100K in the temperature dependence of thermal expansion. The temperature dependences of the 4f -electron contribution to the volume thermal expansion ΔV/V) 4f and the average Eu valence are found to show good scaling in EuNi2P2. © 2013 The Physical Society of Japan.
