    摘要: A magnetoresistance effect element is provided which comprises a substrate on which a first magnetic layer having a thickness of 0.2 to 5 nm which contains cobalt, a second magnetic layer having a thickness of not larger than 5 nm which contains iron or nickel or an alloy thereof, a third magnetic layer having a thickness of 0.2 to 5 nm which contains cobalt and a nonmagnetic layer having a thickness of 0.5 to 5 nm are laminated in this order at least twice, wherein the thickness of the second magnetic layer is not larger than half of the total thickness of the first and third magnetic layers. The element is useful as a magnetoresistance sensor or head.

    摘要: In the method for making the magnetic recording wherein a first magnetic layer is formed on a substrate and a second magnetic layer is formed on the first magnetic layer, before forming the second magnetic layer, accelerated ions are irradiated onto a surface of the first magnetic layer. Thereby, naturally formed oxidized layer and adhered impurity on the first magnetic layer are removed from the surface of the first magnetic layer by ion etching action by the irradiation of ions, and hence a preferable condition of an interface between the first magnetic layer and subsequently formed second magnetic layer is obtained.

    摘要: The method includes applying ions and electrons from an ion gun onto a polymer film while the polymer film is traveling circumferentially along a peripheral surface of a cylindrical can from a supply location to a take-up location of the polymer film relative to the cylindrical drum. The ions and electrons from the ion gun are applied onto a part of the polymer film while it is moving through a position near the supply location of the polymer film relative to the drum at which the polymer film begins to contact the outer peripheral surface of the drum. At a downstream location relative to the drum, electrons are applied from an electron gun onto the polymer film traveling on the drum surface. At a further downstream location relative to the drum, the thin film is deposited, e.g., by vacuum evaporation, on the polymer film travelling on the drum. This method enables a thin film, having no wrinkles and with a high adhesion strength with respect to the polymer film, to be produced in a stable manner.
