Abstract
The magneto-optical spectra (sigma(xx) and omega sigma(xx) in the phot
on energy range 1.2-4.6 eV) of Fe50Co50 thin films are enhanced by the
disorder-order transition, while those of Ni75Fe25 thin film are redu
ced by the transition. We compared the experimental results with the j
oint density of states for each ordered and disordered state. The chan
ges in the omega sigma(xy)(n) spectra through the disorder-order trans
ition were found to be roughly in agreement with the differences of th
e joint density of states between up and down spin states for each sta
te.
