Abstract 57 The layer magnetisation reorientation transition (spin-flop, SF) was studied in an artificial layer antiferromagnet (AF), namely in MgO(0 0 1)/[ Fe(2.6 nm)/Cr(1.3 nm)]20 epitaxial superlattice (SL) by synchrotron Mössbauer reflectometry and Kerr effect (SMOKE). The SF occurs simultaneously in the entire SL stack (bulk SF) in an increasing field of HSF=13 mT along the easy direction parallel to the layer magnetisations. It is recognised by the kink in the SMOKE loop and by the sharp up-rise of the AF Bragg peak in the delayed Mössbauer reflectivity. The moderate value of observed HSF is compared with estimations from a spin-chain model and interpreted as due to intraplane domain-wall motion during SF.

Prompt (a) and TISMR (b d) scans of MgO(0 0 1)/[57Fe(2.6 nm)/Cr(1.3 nm)] superlattice taken in (b): 3 mT, (c): 35.3 mT and (d): repeated 3 mT magnetic fields, respectively. The appearance of the -order AF Bragg peak shows the Ż 20 reorientation of the layer magnetisations at a bulk SF transition field HSF. The system of co-ordinates in the insets is fixed to the substrate. Enlarge Image (6K) 57 Fig. 2. Surface magneto-optical Kerr loops of a superlattice MgO(0 0 1)/[ Fe(2.6 nm)/Cr(1.3 nm)]20. SF occurs around HSF=13 mT only once following a 90° rotation of the substrate relative to the field direction. References 1. F.C. Nötermann, R.L. Stamps, A.S. Carriço and R.E. Camley Phys. Rev.
