We report on the temperature dependence of the 
magnetic hyperfine field
in bcc-Co as measured in Fe/Co multilayers. An anomalous increase of the
hyperfine field with temperature is observed. Below the growth temperature
of the samples, the behaviour can be explained by simple thermal expansion
of the lattice. At 570 K a relaxation of the interplanar distance accounts
for the anomaly. This relaxation is interpreted as an onset to the degeneration
of the forced bcc structure to an energetically more favorable Co-phase.
