Abstract :
The magnetic properties of amorphous CoTi alloys were studied for a wide range of Ti content by magnetization and FMR measurements. The magnetic moment 
per alloy atom, at 4.2°K, decreases linearly with the increase of Ti concentration. The rate of change 
is in good agreement with theoretical predictions. The stiffness constant D deduced from the temperature dependence of the magnetization is linearly correlated with Tc . F.M.R. measurements revealed the existence of an oxygen contaminated surface layer, the thickness of which was determined by ion probe analysis. The S.S.W. spectrum is typical of a soft ferromagnet with highly uniform properties in the bulk of the film. The discrepancies between the value of D deduced from S.S.W. and magnetometer measurements are pointed out.
