I made ellipsometry measurements of a thin film with system structure (Al/Permalloy/Sitall) and got (Psi and Delta) Vs wavelength. I need a recommendation for fitting and get the optical and physical properties of the thin film.

Dear Dr. Hesham

In spite of it is an old paper, but it is useful for your study. From which you can determine the optical constants
Lindquist R. E. and E. Ewald (1963): J. Opt. Soc. of America, 53, 2, 245.
