摘要：

Neutron diffraction studies of MBE-grown (111) EuTe/PbTe superlattices are reported. The EuTe layers exhibit an AF structure consisting of antiferromagnetically coupled (111) spin sheets. The data reveal interlayer magnetic coupling accross PbTe spacers with surprisingly large thicknesses (up to 55 Angstrom), despite the low carrier concentration which rules out any significant RKKY interactions.
