摘要： A scanning-aperture electron microscope system and method in which a radiation source generates a radiation beam that is incident upon a surface of a sample material causing electrons to be ejected from the surface. When magnetic imaging is being performed, a polarization rotator polarization-modulates the radiation beam. A scanning-aperture probe having an aperture is positioned in proxiity to the surface of the sample material so that photoelectrons ejected from the surface of the sample material pass through the aperture. A detector detects the electrons passing through the aperture. The electron detector outputs a signal in response to the detected electrons that is used for imaging magnetic and/or spectroscopic features of the surface of the sample material. The resolution of the imaged features is about equal to a size of the aperture.

摘要： A method for making a patterned magnetic recording disk uses patterned ion implantation of the disk substrate. Energetic ions, such as He, N or Ar ions, are directed to the disk substrate through a mask, preferably a non-contact mask. They are implanted into the substrate, and the process causes localized topographic distortions in the substrate surface. A magnetic layer is then deposited over the substrate in the conventional manner, such as by sputtering. The result is a disk with patterned magnetic regions that are raised above the substrate surface. Because these regions are elevated, they are closer to the recording head in the disk drive and can thus be individually recorded to form discrete magnetic bits. Depending on the type of substrate used, the ion implantation can cause either localized swelling to form pillars or localized compaction to form pits. The patches of magnetic material on the tops of the pillars, or on the substrate surface between the pits, form the discrete magnetic bits.
摘要翻译：用于制造图案化磁记录盘的方法使用盘基片的图案化离子注入。能量离子如He，N或Ar离子通过掩模，优选非接触掩模引导到盘基底。它们被植入衬底中，并且该过程引起衬底表面中的局部地形变形。然后以常规方式例如通过溅射将磁性层沉积在衬底上。结果是具有在衬底表面上方升高的图案化磁区的磁盘。因为这些区域被升高，所以它们更靠近磁盘驱动器中的记录头，因此可以被单独地记录以形成离散磁头。根据所使用的底物的类型，离子注入可导致局部溶胀形成柱状或局部压实形成凹坑。在柱的顶部或凹坑之间的衬底表面上的磁性材料的贴片形成离散的磁性位。

摘要： A horizontal magnetic recording medium that has as its magnetic film a granular film with grains of a chemically-ordered FePt or FePtX (or CoPt or CoPtX) alloy in the tetragonal L1.sub.0 structure uses an etched seed layer beneath the granular film. The granular magnetic film reveals a very high magnetocrystalline anisotropy within the individual grains. The film is produced by sputtering from a single alloy target or cosputtering from several targets. The granular structure and the chemical ordering are controlled by means of sputter parameters, e.g., temperature and deposition rate, and by the use of the etched seed layer that provides a structure for the subsequently sputter-deposited granular magnetic film. The structure of the seed layer is obtained by sputter etching, plasma etching, ion irradiation, or laser irradiation. The magnetic properties, i.e., H.sub.c and areal moment density M.sub.r t, are controlled by the granularity (grain size and grain distribution), the degree of chemical ordering, and the addition of one or more nonmagnetic materials, such as Cr, Ag, Cu, Ta, or B. The resulting granular magnetic film has magnetic properties suitable for application in high-density, horizontal magnetic recording media.
