Abstract
Spin correlations close to the critical concentration for ferromagnetism in HCP CoCr have been studied using SANS and a.c. susceptibility. The critical concentration is 69 at.% Co above which the correlation length does not diverge at Tc but exhibits a scaling behaviour similar to that observed for many inhomogeneous systems.
