Antiferromagnetism in ZnSe/MnSe strained-layer superlattices

Abstract

Neutron diffraction studies of ZnSe/MnSe strained-layer superlattices with individual MnSe layer thicknesses ranging from 3 to 15 monolayers show a second-order transition to type-III antiferromagnetic order. The magnetic reflections indicate a single orientation of the type-III domain, with the tetragonal axis perpendicular to the layer plane and the spins lying within the layer plane.
