Abstract
Artificial lattices with semiconductor spacers are expected to exhibit changes in their magnetic structure owing to the control of their electronic states. The temperature (T) and magnetic-field (Hext) dependence of the in-plane magnetic structure of an [Fe3Si/FeSi2]20 superlattice with a nonmagnetic and semiconducting FeSi2 spacer layer is investigated using magnetization and polarized neutron reflectivity measurements. When Hext = 5 mT, nearly collinear antiferromagnetic (AF) structures are observed from 4 to 298 K. When Hext = 1 T, field-induced fan-like, noncollinear AF structures showing ferromagnetic components along Hext and transverse AF components are observed at low T.
