  • Magnetization reversal in films with biaxial anisotropy

    Publication Year: 1966, Page(s):68 - 73

    Two models of magnetization reversal for the case of films with biaxial anisotropy are considered: 1 ) the coherent rotation model of Stoner and Wohlfarth (S-W) and 2) the noncoherent or wall-motion model of Kondorsky (K). The former has been considered by several authors previously while the latter is developed in the present paper. The (K) model presumes that the anisotropy field is much larger ...

  • A simple low-frequency thin-film magnetometer

    The usual way of plotting hysteresis curves involves the integration of dB/dt , which has many disadvantages at low frequencies, and calls for complicated and expensive instrumentation. The instrument described here is not as accurate as a good vibrating sample magnetometer, but is very simple, inexpensive, and easy to construct and to use. It involves no int... View full abstract»

  • An analog core memory for pulse-width modulated signal

    This paper describes the results of studies on an analog core memory with the aim of applying them to the process controllers. The analog information is stored as the flux level of the square-loop magnetic core. The "write-in" and "read-out" of flux level are achieved by the pulse-width modulation techniques. The storage errors are introduced by the deviations from the ideal square-loop characteri... View full abstract»

  • Interleaved word and bit disturbs in ratchet writing

    Publication Year: 1966, Page(s):85 - 91
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (568 KB)

    Ratchet writing is employed as a means of storing information in certain NDRO memories. This mode of writing permits multiple-word organization. However, when this is done the memory elements are subjected to a new kind of worst-case disturb pattern consisting of interleaved bit- and word-disturb pulses. The interleaved pattern is more destructive than either bit or word disturbs alone. A theory i... View full abstract»

  • A magnetization model for soft ferromagnetic wires

    Publication Year: 1966, Page(s):92 - 99

    When a short segment of a long soft ferromagnetic wire is magnetized, its length and form depend upon the demagnetizing field created by the magnetization reversal in conjunction with the solenoid configuration and certain wire properties. It is shown that a satisfactory explanation of the form of the observed magnetization of such a segment can be developed without considering details of the segm... View full abstract»

  • Theory of NRZ recording

    The width of the transition region between oppositely magnetized regions in nonreturn-to-zero (NRZ) digital recording is calculated by minimizing the energies involved, taking into account to a first approximation the interaction with the read-head. The writing process is neglected and argued to be relatively unimportant. The width is found to be in agreement with all available experimental data o... View full abstract»

  • An analysis of AC controlled push-pull magnetic amplifier with compensating voltage

    Publication Year: 1966, Page(s):110 - 121
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (936 KB)

    An equivalent circuit analysis of an ac controlled push-pull magnetic amplifier is performed, which is compensated with a transistor switching circuit [1] in order to overcome the negative feedback action by the gating induced EMF. The modes of the operation of this new push-pull magnetic amplifier circuit are made clear for cases of various degrees of compensation. The theoretical formulas on bot... View full abstract»

  • The fluxguide--A magnetic circuit component for developing uniform magnetic fields

    The fluxguide is a uniformly magnetized magnetic shell surrounding the air gap between the pole pieces of a magnetic circuit. The uniform magnetization is obtained by varying the thickness of the shell to provide compensation for flux leakage from the outer surface of the shell. Under this condition we have ideally a uniform magnet field within the shell. Experimentally, addition of a fluxguide to... View full abstract»

  • Measurements of magnetostrictive coefficients by means of an optical diffraction technique

    Publication Year: 1966, Page(s):127 - 134

    An experimental procedure for the measurements of the magnetostrictive coefficients of planar, anisotropic, polycrystalline magnetic structures was established. A new optoelectronic method has been conceived and realized by a dynamic modulation of a Fraunhofer diffraction pattern which results when a collimated, monochromatic light beam passes through a slit, one edge of which is simply the end of...
