    Progress made during the past years in the area of magnetooptic data storage by the computer industry has been most impressive. Many material media and physical phenomena have been developed for this particular application. It now appears that a large capacity ( g\sim 10^{10} bits) magnetooptic data store possessing major advantages over the conventional reco... View full abstract»

    The capacity and limitations of fast random-access holographic memory are discussed. Capacities such 1011bits can be envisioned by superposition of holograms in a thick erasable storage material. The organization of the read-write holographic memory provides the possibility of varying the reference beam angle at any given point of the memory plane. View full abstract»

    The general features common to all rotating-sample magnetic measurements are described, and the governing equations are given. A number of cases of special interest are discussed in some detail: these include the measurement of magnetization as a function of field and temperature and the measurement of rotational hysteresis, various kinds of anisotropy, and magnetostriction. The concept of the rot... View full abstract»

  • A compensating method of skew determination in cylindrical thin magnetic films

    Publication Year: 1973, Page(s):110 - 111
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (200 KB)

    A new compensating method for skew measurement in toristor-type cylindrical magnetic films is described. The state of the magnetization vector is scanned with a bipolar magnetic-field pulse and a compensating dc field is applied. Both the magnitude and direction of the skew are obtained.

    The magnetic field distribution in a cylindrical ferromagnetic conductor is determined for the case of a direct current flowing along the axis of the cylinder and a constant external magnetic field applied in a direction transverse to the current flow. The Gauss-Seidel iteration method is employed to obtain the vector potentials for different values of current and external field with the aid of a ... View full abstract»

  • Flux distribution and power loss in the mitered overlap joint in power transformer cores

    Publication Year: 1973, Page(s):114 - 122
    Cited by:  Papers (23)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (904 KB)

    The design of the joints in a power transformer core has a marked influence on the efficiency of the core as a whole. Two experimental cores have been built such that the lengths of their 45° mitered overlaps could be varied from 0 to 2.0 cm. The larger core, with 1.0 m limbs, was used for investigating flux and loss variations and the second, smaller core was used to study how the results mi... View full abstract»

    The total core loss at 15 kG induction of different types of nonoriented lamination steel is described empirically as a single function of thickness, grain size, resistivity, and a quantity related to the preferred orientation of the material. This texture-related quantity is the induction at 30 oersted, B30, divided by the saturation induction, BS. In addition, a linear effe... View full abstract»

    The repulsive force between identical right-circular-cylindrical permanent magnets is calculated, and the ratio of this force to the weight of a magnet is maximized through optimization of magnet size and shape. It is assumed that the magnets are uniformly magnetized along their axes. For magnets of thickness t and radius R...

    The effect of interactions on the saturation remanence of assemblies of identical, uniaxially anisotropic, single-domain particles is calculated using a spatial-mean interaction field. The particle easy-axis directions are assumed known and given by a distribution function. The remanence is determined by finding the magnetization orientation functional of the particle easy-axis orientation which m... View full abstract»

    An experimental investigation has been made of the dependence of the read-back signal on medium thickness and read transducer spacing for magnetic recording particulate disk file systems using saturation recording. The novel technique employed permits the study of the effects of transducer spacing and medium thickness without the need for changing either the medium specimen or the read transducer....
