A new method of obtaining polar Kerr spectra from very thin absorbing films is used to study the thickness dependence of the Curie temperature, compensation temperature and critical behavior of the Fe-subnetwork of amorphous Tb-Fe alloy films. Significant deviations from bulk behavior begin to occur a thickness below about 20 nm.
