The magnetic properties of three homogeneous samples of the weak itinerant ferromagnet Sc{sub 3}In have been determined in the hydrostatic pressure, temperature, and magnetic field ranges 0--6 kbar, 3--300 K, and 0--57 kOe, respectively. The pressure dependence of the Curie temperature {ital T}{sub {ital c}}(P) was determined to 31 kbar. The application of hydrostatic pressure is found to significantly enhance the magnetic properties of Sc{sub 3}In at both low and high temperatures relative to {ital T}{sub {ital c}}. These results contradict a theoretical model by Wohlfarth, according to which the magnetic properties of homogeneous weak itinerant ferromagnets should be weakened under pressure.
