  • Patent number: 4276183
    Abstract: Magnetic material comprising magnetic iron oxide modified with at least about 0.5 weight % cobalt, based on the weight of total product which when combined with a binder at a 75% by weight loading forms a magnetic recording member having an orientation ratio and coercivity value that corresponds to a coordinate value equal to or above the coordinate values on the FIGURE and an M-factor value between about -1.0 and +1.0. The magnetic material is preferred in which the amount of cobalt present is from about 0.5 to about 5.0 weight % based on the weight of total product and in which chromium is also present in an amount of from about 0.1 to about 0.3 weight percent based on the weight of total product.
