Neutron small-angle scattering from palladium alloys

The dependence of the neutron small-angle scattering intensities on an applied magnetic field and on the temperature has been investigated for a number of dilute PdFe and PdMn alloys. Critical magnetic scattering was observed at small q values over a wide temperature range. Applying a magnetic field of 4 kOe was usually sufficient to suppress the critical scattering completely, so that from the anisotropy of the residual magnetic scattering proper values for the giant moments could be deduced.
