Expressions are obtained for the change (jump) of the magnetic moment of the conduction electrons following a transition from the ferromagnetic into the antiferromagnetic phase. It is shown that the absolute value and the sign of this jump depend substantially on the topology of that Fermi-surface section which is responsible for the formation of the helicoidal magnetic structure. Good qualitative agreement is observed between the relative change of the magnetic moment of the conduction electrons and the relative change of the hyperfine field at the diamagnetic-impurity nuclei in a dysprosium matrix.
