    The purpose of this study is to investigate the leakage field from the auxiliary layer to the recording layer in an exchange-coupled multilayered magneto-optical medium. In order to estimate the leakage field, test media, in which the auxiliary layer was deposited on the recording layer with a nonmagnetic layer intervening, were prepared. The leakage field was determined as the difference in the t... View full abstract»

    The magnetic properties of silicon steel sheet under conditions of two-dimensional excitation (circular, elliptic and alternating the rotation direction) were investigated. "Two-dimensional magnetic measurement" is a generic term introduced recently to describe the measurement of magnetic properties of a specimen under conditions of a rotating magnetic induction. The two-dimensional magnetic prope... View full abstract»

    The frequency dependence of the permeability, jU^, in amorphous Co-Fe- Si-B wires was investigated as a function of the wire diameter, annealing temperature, tensile stress and drawing parameters. Results show that the level of ¿i and the critical frequency for holding ¿i constant depend mainly on the wire diameter, suggesting that eddy currents affect ¿i at hig... View full abstract»

    The initial permeability of Fe-Si polycrystalline thin films was investigated. Based on calculations of the magneto-crystalline anisotropy and initial permeability which assume that the magnetization is confined to a certain crystal plane, Fe-Si polycrystalline thin films oriented with the (111) plane parallel to the film plane are ' expected to have a high permeability of about 5000. Fe-6.9 wt% S... View full abstract»

    Magnetic thin films of FeTa-N-O were prepared by using facing-target type dc magnetron sputtering in Ar+N2+O2 plasma. The magnetic and structural properties were investigated as a function of the flow rates of the O2 and N2 introduced into the argon atmosphere. A high Bs (19 kG) and soft magnetic properties (Hc¿0.3 Oe, ¿¿3000) we... View full abstract»

    The dependence of the soft magnetic properties of sputtered (Fe1-xCox)1-y films (0¿X¿1.0, 0¿Y¿0.2 in weight fractions) on the composition and annealing temperature was studied. Films with Y¿0.16 were amorphous, while films with Y¿0.16 have bec structure for 0¿X¿0.8 and fcc structure for 0.8¿X¿1.0. The lattice constant of the bec films increases with Nb co...

    The relationship between anisotropic magnetoresistance and the Hall effect was studied for fcc Ni-Co binary alloy thin films. The maximum value of ¿¿/¿0 was 5.3%, obtained for 75 at % Ni-Co alloy. At this alloy composition, the ordinary Hall coefficient R0 was ¿2.0×l0~12 V- cm/A-Oe, and the extraordinary Hall coefficient R3 was 0.6×10¿10 V-cm/A-G,... View full abstract»

    The magnetoresistance of Ni-Fe-Co+M (M= Ti, V, Cr, Mn, Cu, Ag, Nb) films evaporation-deposited at a substrate temperature of 350°C was studied. By adding a fourth element, the film magneto-resistance is decreased, especially when Cr is added. The results show that the decrease corresponds well with the change in saturation magnetization by adding the fourth element. The thermal stability of the m... View full abstract»

    A method for highly precise measurement of the permeability of thin films in the VHF frequency range has been developed. The permeability of a film sample in a strong magnetic field can be predicted with very high accuracy; this permeability is then used as the standard of a measurement system. Multilayer films with various spacer thicknesses and a FeZrN micro-crystalline film were measured. Resul... View full abstract»

    CoOx thin films with perpendicular magnetic anisotropy (PMA) were prepared at room temperature by the reactive facing-target sputtering technique. We investigated the PMA, coercivity and static magnetization process of the film samples, with the following results. (1) CoOx films with a columnar structure are composed of hep Co and fcc CoO. (2) The highest perpendicular anisot... View full abstract»

    Ni-Zn-ferrite thin films were formed on glass substrate by a laser ablation method employing a KrF excimer laser at wave-length 248 nm and frequency 15 Hz. Film was deposited on substrate at room temperature, 200°C and 350°C, to a thickness of 2 ¿m. Ni-Zn-ferrite films thus prepared had the spinel structure when the substrate temperature was raised to 200°C. The saturation magnetic flux densit... View full abstract»
