Abstract

The investigation of current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) devices having half-metallic Fe3O4 for their magnetic layers was presented. The investigation was done along with fabrication of Fe3O4 films on Au layers at low temperature (523 K). A decrease in the magnetoresistance ratio was found with the decrease in Fe3O4 thickness for CPP-GMR devices comprised on Ni80Fe20/Au/Fe3O4 trilayers.
