Magnetic dipole strength functions have been deduced from a large number of M1 transition strengths calculated within the shell model for the nuclides 94Mo, 95Mo, and 90Zr. An enhancement of M1 strength toward low energy has been found for all nuclides considered. This enhancement supports results of recent (3He,3He') and (d,p) experiments, but is at variance with analytical M1 strength functions currently given in reaction-data libraries and used in statistical-reaction codes.
