Popis:	(Received 26 November 199 1) In a recent letter’ an elementary formula was derived for the complex magneto-optical polar Kerr rotation 0k from a model superlattice. The calculations apply, at nor- mal incidence only, to a semi-infinite two component su- perlattice in the specific case where the refractive indices nl and nz of the two media (labeled 1 and 2) are equal. An approximate formula is also given for flk when n1 and n2 differ by a small amount A given by A= (n2-nl)/nl. (1) The only conditions for the applicability of the formula are that 2r[nlldl4 and 27-r 1 n2 d24 (2) where
