  • Patent number: 9396742
    Abstract: A magnetic read transducer including a magnetoresistive sensor is described, as well as a fabrication method thereof. The magnetoresistive sensor includes a cap layer overlaying a free layer. The cap layer is situated with a first thickness to absorb boron from the free layer. The magnetoresistive sensor is annealed, and boron is diffused from the free layer and absorbed by the cap layer, improving the magnetic performance of the free layer. The cap layer thickness is then reduced to a second thickness, thereby reducing the shield-to-shield (SS) stack spacing of the magnetoresistive sensor and allowing for increased areal recording density.

  • Patent number: 9287557
    Abstract: When an active material with low ionic conductivity and low electric conductivity is used in a nonaqueous electrolyte secondary battery such as a lithium ion battery, it is necessary to reduce the sizes of particles; however, reduction in sizes of particles leads to a decrease in electrode density. Active material particles of an oxide, which include a transition metal and have an average size of 5 nm to 50 nm, are mixed with an electrolyte, a binder, and the like to form a slurry, and the slurry is applied to a collector. Then, the collector coated with the slurry is exposed to a magnetic field. Accordingly, the active material particles aggregate so that the density thereof increases. Alternatively, the active material particles may be applied to the collector in a magnetic field. The use of the aggregating active material particles makes it possible to increase the electrode density.
