我们通过静水压力下详细的交流磁化率和量热研究证明，YbCu2Si2 可能在高压下呈铁磁性有序。 (p,H,T) 相图显示，转变温度随着压力的增加而增加，但也随着施加的磁场的增加而增加。我们认为许多镱系统可能表现出铁磁性的趋势，并讨论了其可能的原因。我们还研究了其影响，包括 YbCu2Si2 和其他 Yb 化合物进一步研究铁磁临界点附近可能出现的丰富物理性质的潜力。
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 towards 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.
