    Amorphous GdxFe1-x(0 < x < 0.35) thin films were prepared by RF cosputtering using an iron target covered partially with small gadolinium pieces. The composition dependences of saturation magnetization, hysteresis curves, and domain structures were studied. Spark-like domains were observed when the magnetization was reversed from saturation. The uniaxial anisotropy was ... View full abstract»

    Thermomagnetic writing on low-temperature phase MnBi films was investigated. By applying short laser pulses, the undesirable transformation to the quenched high-temperature phase is inhibited. The low-temperature phase proved to be stable when heated for magnetic switching with pulses shorter than 10 μs. The transient temperature during laser heating of a 20 μm diameter film spot was det... View full abstract»

  • Monte Carlo and series expansion investigations of magnetic surfaces

    The presence of a free surface leads to an inhomogeneous distribution of the local magnetization and other quantities describing the magnetic state of the system. After a brief outline of a general thermodynamic theory, the mean field treatment is discussed and shown to be inconsistent with a more general scaling theory, even if one uses a temperature-dependent extrapolation length. More reliable ... View full abstract»

  • Surface magnetism and spin polarized photoemission

    Publication Year: 1976, Page(s):74 - 80
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (704 KB)

    The spin polarized photoemission experiment is shortly described. Some of the more serious difficulties in analyzing the data are mentioned, with special emphasis on the influence of the surface on the polarization of the emitted electron beam. Three measurements: 1) determination of the escape depth of the photoelectrons, 2) spin polarized photoemission from EuO, and 3) Ni, serve as examples for ... View full abstract»

  • Magnetooptic spectroscopy of EuS, EuSe, and EuTe

    Publication Year: 1976, Page(s):81 - 85
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (488 KB)

    The absorption Coefficient and the interband Faraday rotation of EuS, EuSe, and EuTe thin films have been measured as a function of the photon energy (1-6 eV), the temperature (2.7-300 K), and the applied magnetic field (0.1-11.5 kOe). From the Faraday rotation (FR) we compute the circular magnetic dichroism and from both and the optical constants n and View full abstract»

    Mössbauer experiments were made utilizing Co57or Fe57as a microprobe for studying the magnetic properties of ferromagnetic metal surfaces. For the emission spectroscopy, carrier-free Co57atoms were electrodeposited on a surface of bulk iron. The absorption spectroscopy was applied to a sample whose surface was selectively enriched with Fe57. In both... View full abstract»

    The theory of phase transitions in magnetic systems with surfaces is reviewed. Results of the phenomenological Landau-Ginzburg theory as well the scaling theory are briefly presented and compared with those obtained for particular microscopic models. Possibilities of special kinds of magnetic phase transitions in systems with surfaces are also presented. View full abstract»

  • Stress sensitivity of the A.C. magnetic properties of permendur after various heat treatments

    Permendur in laminated form is often used in magnetic cores of machines and transformers where it might be subjected to mechanical stress. Measurements have been made to determine to what extent the a.c. iron loss and magnetostriction are affected by such linear stress. Magnetic properties were found to be dependent on heat treatment over the temperature range 400°C to 900°C. The loss of... View full abstract»

  • Models for I and T pattern permalloy bars based upon bitter pattern observation of domain wall movements

    The magnetostatic fields of the I and T pattern Permalloy overlay bars are analyzed by proposing a model based on the Bitter pattern observation of the domain wall structure in Permalloy bars. The magnetic charges that appear on the 90° domain walls are assumed to be the sources of the magnetic fields of the bars. The model has a two-dimensional reaction to an applied rotating in-plane field ... View full abstract»

    The known expressions for magnetic energy associated with domain structures are used to calculate magnetization curves and magnetic hysteresis loops of polycrystalline ferromagnetic bodies when they are subjected to either tension or compression. Reversible and irreversible boundary displacement and domain rotation have been taken into account. The model used permits a qualitative description of t... View full abstract»

    Relative humidity has been recognized as an important environmental factor in many head-tape interface phenomena such as headwear, friction, staining, and tape shed. Accordingly, the relative humidity is usually specified in many applications of tape use, especially when tape recorders are enclosed in hermetically sealed cases. Normally, the relative humidity is believed regulated by humidificatio... View full abstract»
