摘要：

We have studied the pressure dependence of the magnetization of single crystalline CeSi1.81. At ambient pressure, ferromagnetism develops below T-C=9.5 K. Below similar to 5 K an additional shoulder in low-field hysteresis loops and a metamagnetic crossover around 4 T suggest the appearance of an additional magnetic modulation to the ferromagnetic state. The suppression of the magnetic order in CeSi1.81 as function of temperature at ambient pressure and as function of pressure at low temperature are in remarkable qualitative agreement. The continuous suppression of the ordered moment at p(c)approximate to 13.1 kbar suggests the existence of a ferromagnetic quantum critical point in this material.
