A. Ziegler et R. Bottner, THE INTERPRETATION OF SPIN-POLARIZED PHOTOEMISSION SPECTRA BY THE SPIN-SPIRAL MODEL - APPLICATION TO MEASUREMENTS ON NI(111), Journal of physics. Condensed matter, 6(19), 1994, pp. 3609-3617
A generalization of the spin-spiral model developed previously to inte
rpret non-spin-polarized photoemission data on ferromagnetic metals to
the spin-polarized case is applied to measurements on nickel by Kampe
r et al. This method is easy to use and in contrast to the cumbersome
random-cluster model leads to meaningful results for the magnetic shor
t-range order ranging from 20 angstrom to 60 angstrom close to T(c).
