Abstract
Magnetic and magneto-optical properties of amorphous CoxY1-x (x = 0.80, 0.35) films (thickness range : 50- 1 000 Å) with Mo overlayers are studied. Transverse biased initial susceptibility measurements are reported. The structure constant S increases as the thickness decreases, i.e. : S = 0.04 and 0.15 erg/cm2 for 1 000 Å and 50 Å respectively. Surface effects on Co0.35Y0.65 are discussed.
