N2 - Pressure-induced anomalies around the critical end point in an itinerant-electron metamagnetic La (Fe0.89 Si0.11) 13 compound have been investigated. The Curie temperature TC is decreased from 189 to 0 K by applying a critical pressure pC =1.3 GPa. The relation TC (pC -p) 0.5 is explained by the spin-fluctuation theory based on the Landau expansion. A susceptibility maximum appears at Tmax ∼70 K above p=1.2 GPa. On the other hand, the critical point (T0, μ0 H0) of the transition is lowered to T0 =14 K and μ0 H0 =2.5 T at 1.4 GPa, showing no static ferromagnetic moment in the field-induced state below T0.
