Polarized neutron scattering techniques have been used to study the spatial distribution and temperature dependence of the magnetization induced in single crystals of UPt3, UBe13, and CeCu2Si2 by an externally applied magnetic field. We find that (a) the induced magnetization in the normal low-temperature state is predominatly of f-electronic character and that (b) the generalized electronic susceptibility (Q,0) where Q is a reciprocal-lattice vector), obtained by measurements with H
