Use of germanium coated substrates for electrodeposited permalloy thin films used as high speed memories remarkably improves the magnetic properties and their reproducibility. Effective features of the germanium coated substrates (germanium/silver/glass) were investigated in comparison with the silver coated substrates (silver/glass and silver/germanium/silver/glass), using a B-H loop tracer, an electron microscope and an X-ray diffractometer. The experimental results suggest that the advantage of germanium coated substrates comes from the amorphous structure of a germanium layer.
