Abstract
UPtAl exhibits ferromagnetic ordering (TC = 42.5 K) of uranium 5f-electron moments. The magnetic ordering transition is accompanied by an electrical-resistivity (ρ) anomaly at Curie temperature (TC). We report on resistivity measurements performed in a wide temperature range on a UPtAl single crystal under hydrostatic pressures p ≤8 GPa. The initial increase of TC with p becomes gradually reduced for p > 2 GPa. The maximum TC value is reached between 4 and 6 GPa that is followed by a decrease of TC beyond 6 GPa. The latter result is attributed to the approaching collapse of U 5f moment ferromagnetism.
