    The near field of a fully turbulent circular jet (1985)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 28 (1985), S. 3703-3704 
    Details
    ISSN: 1089-7666

    Topics: Physics
    Notes: The near-field measurement of fully turbulent jets discharged from a straight circular pipe indicates the presence of quasiperiodic velocity perturbations. The Strouhal number based on the predominant frequency falls in the range of the preferred mode for the jet with a potential core and has an asymptotic value of 0.38 in the high Reynolds number regime. Regular perturbations are not observed in the mixing region immediately downstream from the pipe exit.

    Soft magnetic properties of FeRuGaSi alloy films: SOFMAX (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 64 (1988), S. 772-779 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: To advance new soft magnetic materials of an FeGaSi alloy into the commercial world, improvements on various properties were designed by introducing additive elements without sacrificing its high saturation magnetic induction. The detailed studies on the diversified properties, such as saturation magnetic induction, film internal stress, wear resistivity, and so on, were performed. High-frequency permeability of the laminated structure film was also investigated. As a result, the Ru-added FeRuGaSi alloy films, whose typical compositions are Fe72Ru4Ga7Si17 and Fe68Ru8Ga7Si17 (at. %), prove to be excellent soft magnetic materials especially appropriate for the magnetic recording/playback head core use.

    High-frequency permeability in double-layered structure of amorphous Co-Ta-Zr films (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 63 (1988), S. 5424-5426 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The high-frequency permeability of amorphous Co-Ta-Zr films was studied and the frequency dependence was described in terms of the eddy-current-loss formula. For the double-layered structure intervened with SiO2 film, the degradation of the permeability became apparent with the decrease of SiO2 thickness.

    New crystalline soft magnetic alloy with high saturation magnetization (invited) (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 3514-3519 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Extensive study was made on Fe-base crystalline alloys in search for new soft magnetic materials with high saturation magnetization by means of sputtering technique. It revealed that newly found FeGaSi and FeAlGe alloy systems possessed excellent soft magnetic properties with remarkably higher saturation magnetization. These new alloy films, annealed in vacuum at 500 °C for 1 h, show the magnetic properties of Bs=13 and 15 kG, Hc=0.09 and 0.20 Oe, and μ1 MHz=2000 and 1800 for the FeGaSi and FeAlGe alloy films of 2 μm in thickness, respectively. These values are superior to those of FeAlSi (sendust) alloy which is a typical soft magnetic material with high saturation magnetization. Results of the Co-added systems of FeCoGaSi and FeCoAlGe alloys are also presented. Discussions are given on various systems of Fe base crystalline alloy films studied, which are classified into four types of groups with respect to magnetic softness.

    Magnetic and other properties and sputtering behavior of Co-base amorphous alloy films (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 2983-2992 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Magnetic and other properties of Co-base amorphous alloy films prepared by sputtering are investigated. A detailed magnetic phase diagram with saturation magnetic flux density, crystallization temperature, and zero-magnetostrictive line on Co-Ta-Zr amorphous alloys were obtained, and the technical knowhow to make a film with well-reproducible characteristics by widely changing the sputtering conditions was related with these physical properties. Especially on alloy sputtering, a phenomenological model for elucidating a composition difference between film and target is presented. After these studies, the film characteristics of Bs=12 kG, Tx=450 °C, ||λs||〈10−8, Hc〈10 mOe, and permeabilities of μ(1 MHz)=7000, μ(100 MHz)=2000 for the single film of 2 μm in thickness and of μ(1 MHz)=4000, μ(100 MHz)=800 for the insulator-sandwiched multilayered film of 10 μm are obtained, and these well-balanced values enable us to apply the materials for high-frequency recording head.

    Soft magnetic Fe-Al-N/Si-N multilayered film with high thermal stability (1989)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 54 (1989), S. 1181-1182 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: An attempt to obtain soft magnetic materials with high saturation magnetic flux density and thermal stability has been carried out with respect to a multilayered type of films containing Fe-N prepared by two-source magnetron rf sputtering. The addition of small amounts of elements such as Al is effective in improving soft magnetic properties of Fe-N films. Multilayered films of Fe-Al-N intervened by thin Si-N layers showed softer magnetic properties than the Fe-Al-N single layer films and also showed high thermal stability. Typically, Fe-Al-N (500 A(ring))/Si-N (12 A(ring)) multilayered films exhibited a saturation magnetic flux density of 20 kG, a coercivity Hc of 0.3 Oe, and a permeability μ of 1900 at 5 MHz after annealing at 550 °C for 1 h.
