摘要：
We report on interlayer coupling in [Ern(Er)|Tbn(Tb)] superlattices. By means of neutron diffraction, helix-like and conical magnetic structures are observed in an [Er20|Tb5] sample. These structures are correlated across terbium layers at low temperatures, where bulk terbium is ferromagnetic. Moreover, resonant X-ray magnetic scattering gives clear evidence that the 5d conduction band of terbium is polarized according to the erbium magnetic structure.
