Antiferromagnetic ordering in MnSe/ZnSe multilayers

Abstract
We report neutron diffraction studies of zinc‐blende strained MnSe/ZnSe superlattices. Such systems are examples of a fcc Heisenberg antiferromagnet of the third kind. The results show clearly long‐range order in the MnSe layer plane, and no magnetic coupling across the passive layers. The strain affects the relative domain population. Measurements of the diffracted intensity versus T show that the AF phase transition in the MnSe layers is of second order with TM = 107 ± 5 K.
