1. To our knowledge the term “magnetic lattice engineering” was introduced by Dr. H. Arend at one of the “Informal Meetings on Halide Layer Perovskites”, organised by him at the E.T.H.-Zürich, 1976–1978.
2. For an overview of the theory, the reader may consult the various volumes in the series: “Phase Transitions and Cricical Phenomena”, ed. C. Domb and M.S. Green, New York, Academic Press, 1972, or the book by H.E. Stanley: “Introduction to Phase Transitions and Critical Phenomena”, Clarendon Press, Oxford, 1971.
3. For a review of experimental work prior to 1974 the reader might consult e.g. L.J. de Jongh and A.R. Miedema. Miedema, “Experiments on simple magnetic model systems”, Taylor and Francis, London, 1974, (also: Adv. Phys. 23 (1974) pp. 1–260 ).
