Abstract
Time-dependent magnetisation and magnetic interactions have been inves tigated on (Co-Cr-Ta)/Cr thin films, The time dependence coefficient ( S) normalised to saturation magnetisation decreased with a reduction o f the magnetic film thickness. Magnetic films which had large positive interactions and a coercive squareness (S) of more than 0.95 showed 'Richter type' decay of demagnetisation. However, when S was less tha n 0.91, magnetisation decreased proportionally to logarithmic time (lo g t) during an applied field.
