    摘要: A method for preparing a magnetic recording medium includes the steps of providing a substrate, providing an alloy composite target attaching thereon Co and Fe pellets to modify the composition of this magnetic recording medium, and utilizing the target to form a (Co,Mn) modified .gamma.-Fe.sub.2 O.sub.3 thin film on the substrate under controlled conditions. Such method can provide a magnetic recording medium which is cost-effective and has a better SNR, a better resistance to corrosion and a high coercivity.

    摘要: A method for preparing a magnetic recording medium includes the following steps of providing a substrate; providing a solution consisting essentially of ions of cobalt, manganese and iron in deionized water; and preheating the substrate and spraying the solution onto the preheated substrate at an elevated temperature to uniformly distribute droplets thereon and form a magnetic recording medium film on the subtrate. Such method can prepare a magnetic thin film which has a high recording density and is cost-effective.

    摘要: The non-acicular modified maghemite and magnetite have high coercivity of, for the maghemite, up to 2200 Oe, saturation and residual magnetization of 63-85 emu/g and 43-52 emu/g, respectively; for the magnetite, the corresponding values are 800-1600 Oe, 82-87 emu/g, and 44-51 emu/g, respectively; while retaining same squareness ratio and same chemistry with conventional iron oxides, fine particle size of around 50 nm, easier dispersion and coating, invaried properties after curing, and low value of temperature coefficient of coercivity (0.24-0.37%/.degree. C. for the maghemite and 0.20-0.33%/.degree. C. for the magnetite), have been invented. They are thus especially suitable for high density recording. The modified maghemite and magnetite are prepared by precipitating from aqueous solution containing Fe, Mn, Co and Zn ions at proper ratio using an organic alkali as precipitant, followed by specific heat treatment sequences.
