The Curie point and spontaneous magnetization of weakly ferromagnetic Y(Co{sub 1{minus}{ital x}}Al{sub {ital x}}){sub 2} alloys with {ital x}{similar to}0.15 is shown to decrease rapidly with increasing pressure, in agreement with the theory of weak itinerant ferromagnetism. Forced magnetostriction measurements on Sc{sub 3}In, however, confirm that the magnetization at 4.2 K in a field of {similar to}2 T increases with pressure.
