Description

Lu substitutions for U (up to 30%) in UPdSn lead to a linear decrease of the lattice volume. After the initial decrease, the magnetic ordering temperature approximates to 25 K. The U-effective moment weakly decreases, whereas the paramagnetic Curie temperature becomes progressively more negative. The γ-coefficient (5 mJ mol-1 K2 for UPdSn) dramatically increases to 78 mJ mol-1 K2 in U0.85Lu0.15PdSn proving that the low γ-value in the parent compound is an accidental feature of the 5f band and not a fingerprint of the 5f localization.
