Structural and electronic properties of YPd5Al2

We present a study of structural and electronic properties of YPd5Al2. Specific-heat measurements reveal a relatively low Sommerfeld coefficient of the electronic contribution γ=4.1 mJ mol−1 K−2. No superconductivity is found down to 0.4 K. First-principles electronic-structure calculations based on density-functional theory have been performed and have been compared with available experimental structural and electronic data.
