    Initial permeabilities of Co-Zr-Nb amorphous single and multilayered films were measured in the frequency range 1-250 MHz. The results are correlated to those of anisotropy dispersion measurements. The multilayered films are relatively free from demagnetizing effects, which leads to good frequency characteristics of the permeability. View full abstract»

    Packaged magnetic bubble test circuits made with 4-µm period ion-implanted circuits were operated over -55° to +110°C. The circuits used bidirectional transfer and nondestructive detection and were made on bismuth-containing magnetic garnet films. Passivated circuits that incorporated an improved transfer conductor design were operated on films with higher Gilbert damping parameters... View full abstract»

    The effect of grain size on core loss and permeability was studied in three heats of silicon-free motor lamination steel. Grain sizes in the final test specimens ranged from 7 to 1360 µm. The core loss and permeability were measured at 10 and 15 kG ac, and 15 kG dc. Regression equations were constructed which took account of the effects of major changes in grain size as well as of minor varia... View full abstract»

    The determination of electromagnetic fields in permanent magnet linear synchronous machines (PMLSM's) to form the basis for the evaluation of forces and parameters of PMLSM'S (to be presented in a subsequent paper) is discussed. Analytical techniques applied to permanent magnet rotary synchronous machines are modified and adapted to PMLSM's. Fields are determined analytically in a single-sided PML... View full abstract»

  • Calculation of the eddy current distribution in the disk of single-phase kilowatt-hour meter by variational method

    Publication Year: 1986, Page(s):113 - 117

    A method based on variational principles has been developed for the computation of the eddy current distribution and hence the driving torque of single-phase kilowatt-hour meters. The airgap field due to the voltage and current coils in the absence of the disk is presumed to be given, and the resultant air-gap field, as well as the eddy currents induced by it, are determined. The reaction field of... View full abstract»

    A method was developed to design high-bandwidth single-ended variable-reluctance position sensors with high accuracy and extremely low temperature drift for use in magnetic bearing control systems. The method was used to design a hermetic radial position sensor with a position sensitivity ( {1/L_{0}}{dL/dx} ) of 1 percent/µm over the range of 0-50 µ... View full abstract»

  • Low specific capacitance by ion-beam oxidation of Niobium-based Josephson tunnel junctions

    Publication Year: 1986, Page(s):124 - 127

    Josephson tunnel junctions were fabricated on niobium by ion-beam oxidation where an oxide thickness independent of the processing time can be achieved. Low specific capacitance of about 5 µF/ cm2at a maximum current density of 1 kA/cm2have been measured via junction and interferometer resonances. A model for the structure of those low-capacitance barriers is proposed. View full abstract»

    The magnetic field strengths and magnetizations of an assembly of magnetic (monocomponent) particles in a constant external field has been calculated. Due to the equilibrium configuration of the particles, forming chains or treelike structures, a one-dimensional approach has been employed. Using the dipole approximation, the problem can be cast as an eigenvalue problem, whose solution yields the m... View full abstract»
