  • Abstract
    An investigation is conducted of strong and weak stripe domains which appear in obliquely deposited NiCo films above a critical thickness for various compositions and angles of deposition in order to test the ability of such structures for information storage. It is shown that a modulation of this structure is possible, especially for the applied field perpendicular to the stripe direction. Materials with higher coercivity are needed for application. For this purpose it is desirable to modify the preparation conditions (e.g. use of Cr sublayer), which could result in a less continuous media. The question is whether in such a media the stripe domains would still exist. New ideas developed in the course of this work are the opportunity to use weak stripe domains of alternate polarity for Ni-rich alloys and the ability of the isolated bubblelike domain obtained at high field for cobalt-rich films to be used as information storage
