Beneath a general electromagnetic characterization of the sandwich layers, measuring the magnetization curve of the assembled video-head allows to detect remanence and coercivity. The eddy current distributions have been also visualized by high resolution thermography. The described measuring methods allow conclusions for the optimization of many parameters of the investigated amorphous CoZrNb sandwich heads.
