Abstract
Neutron scattering measurements on the heavy fermion system CeSi1.76Cu0.24 confirm a phase transition to ferromagnetic order below Tc=8 K. The ordered moment μ= 0.62±0.05 μB is about four times smaller than the effective moment above Tc and agrees well with the saturation moment determined by dc-magnetization measurements. The moments lie in the basal plane of the tetragonal unit cell. The very weak critical magnetic scattering suggests a new type of local moment formation below Tc.
