Abstract
We have performed measurements of the decay of a signal recorded on single layer CoCr films using a thin film ring head. These results are compared with data obtained by magnetometry of magnetization decays in uniformly saturated samples. The importance of the demagnetizing fields on these measurments is discussed briefly.
