The well known fact that the shape of magnetic hysteresis loop (MHL) is closely related with relaxation phenomena, is documented on a wide range of different pinning structures. It is shown that the normalized relaxation rate can be directly calculated from characteristics of the MHL. In the case of known additive contributions to the global moment, the relaxation behaviour is accessible for these individual pinning mechanisms. Thus relaxation studies have exactly the same information value as magnetic hysteresis curves.
