Abstract
The interaction between magnetism and superconductivity is investigated wit hin the theory of superconductivity for electrons in magnetic Bloch-states. We show that the presence of an incommensurate helical magnetic structure suppresses the superconducting order parameter only slightly, via the reduc tion of the effective attraction. Consequences for the upper-critical-field curve of HoNi2B2C and related compounds are discussed.
