Angle-resolved photoemission studies of c(2 x 2)MnCu/Cu(0 0 1) and pgg(4 x 2)Mn/Cu(0 0 1) prepared by in situ deposition of Mn on Cu(0 0 1) are reported. For the c(2 x 2) superstructure, the Mn 3d-derived band is found at 3.0 eV binding energy at the <(<Gamma>)over bar>(e(2x2)) of the second surface Brillouin zone. An identical energy position is observed for the pgg(4 x 2) structure indicating the presence of the same high-spin ground state as in the c(2 x 2). (C) 2001 Elsevier Science B.V. All rights reserved.
