【 摘 要 】

We demonstrate from detailed ac-susceptibility and calorimetry studies under hydrostatic pressure that YbCu2Si2 probably orders ferromagnetically at high pressure. The (p, H, T) phase diagram shows that the transition temperature increases with pressure but also with an applied magnetic field. We suggest that many ytterbium systems may show a trend toward ferromagnetism, and we discuss the possible reasons for this. We also examine the implications, including the potential of YbCu2Si2 and other Yb compounds, for further studies of the rich physical properties that may occur near a ferromagnetic critical point.
