Thin coherent metal films of Co–Cr alloys on Si or glass substrates were used for high density magnetic storage media. They were made by sputtering or evaporation. Variation of the deposition parameters will change the micro structure especially the texture of the thin magnetic layers. We could relate the crystallographic data (rocking curves and pole figures) with the magnetic data (hysteresis loops). Correlations between deposition parameters and crystallographic and magnetic investigations will be discussed in detail.
