    Polycrystalline Eu1-xGdxS films (0 < x < 0.35 and x = 1; thickness is 40 to 600 nm) were prepared by electron-beam and flash evaporation onto heated substrates. The electrical and magnetic properties of these films were investigated through resistivity and hysteresis measurements at temperatures between 4 and 300 K, with a magnetic field, B, of 0.4 Tesla. After a short ... View full abstract»

  • Ferromagnetic domains in EuS investigated by low-temperature Lorentz microscopy

    Publication Year: 1973, Page(s):9 - 12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1016 KB)

    Thin films of EuS, prepared by electron beam evaporation, were investigated by Lorentz microscopy in a special low-temperature object stage. In the thermally demagnetized state of an isotropic film, a multidomain configuration is observed with the smallest detectable domain size being about 200 nm. In the ac-demagnetized state, the domain configuration is similar to the configuration during a magn... View full abstract»

  • Static wall coercive force in ferromagnetic thin films

    Publication Year: 1973, Page(s):17 - 21

    The static wall coercive force of thin ferromagnetic films has been calculated from a model of conservative wall energy. The spatial dependence of the wall energy γwis assumed to be given by the mean value of the local anisotropy energy, averaged over a coupling volume of the wall. The result of the calculation shows that ... View full abstract»

  • Surface modes in magnetic thin films and in spin wave resonance

    Of late, the number of papers on magnetic surface states has greatly increased since the experimental detection of these states has been proven to open up a highly promising source of abundant data on the magnetic properties of materials. Spin wave resonance (SWR)-an effect observed in thin ferromagnetic films-is well adapted for such detection. In this paper, we are concerned with the theoretical... View full abstract»

  • A multilevel core counter and its use

    Publication Year: 1973, Page(s):27 - 31
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (512 KB)

    Magnetic accumulating core counters having large capacity and good linearity can be built by using the flux flyback in rectangular-hysteresis-loop cores for forming constant flux increments. Such counters can be used as analog memory and adaptive elements for building contactless controllable linear resistors with memory, etc. Their use in accumulating logical matrices for statistical processing o...

  • High-density NDRO magnetic-thin-film memory devices

    Publication Year: 1973, Page(s):31 - 36
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (608 KB)

    High-density thin-magnetic-film memory devices using double-layer storage films with NDRO properties were designed and tested. Use of the two double-layer films-one on the bottom and the other on the top of the bit-sense line-produced a structure that allows flux closure in such a way as to make possible a high-density film array. The devices tested were experimental arrays with densities of 4400 ... View full abstract»

  • Thin-magnetic-film general-purpose uniform array based on controlled domain motion

    Publication Year: 1973, Page(s):36 - 38
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (368 KB)

    Thin-film uniform arrays (UA's) are general purpose, easy to produce, and reliable even when implementing complex logic functions. The use of controlled domain motion in narrow channels of low coercive force, formed in a high-coercive-force film, may serve as the basis for the implementation of large uniform programmable logic arrays with memory which feature information storage immune to power su...

    Word currents in the batch fabricated THEMIS store are supplied by magnetic selection needles closely integrated with the storage elements. The selection needle behaves like the well-known switch core. The word current generated is a function of many parameters and tolerances because of interactions between the storage elements and selection needles. This paper discusses these interactions in deta... View full abstract»

    Knowledge of the internal magnetization distributions M(r) of polarizable media allows straightforward calculation of fields for any configuration which includes these media. Although useful calculations have been made using an assumed M(r) , little work directed at calculating M(r)... View full abstract»

    Determination of Joule magnetostriction by the method of tensile strain measurement has a lower limit of about 10-6because of error strains clue to magnetostatic forces and changes in temperature. It is shown that these disturbances can be eliminated by measuring shear strains induced in thin-walled tubes by helical magnetic fields. By a resonance method, the measurement of the magnetos...
