de Haas--van Alphen measurements are reported for the ferromagnetic actinide compounds U/sub 3/P/sub 4/ and U/sub 3/As/sub 4/. The large effective masses indicate f-electron interaction with conduction bands. The data are interpreted in terms of a semimetallic band structure producing a large electron sheet at point GAMMA which is compensated by several smaller hole pockets along the GAMMA--P line. The measured internal field is much smaller than expected on the basis of magnetization measurements. Several discrepancies with other measurements point to additional unobserved pieces of the Fermi surface.
