    This paper presents a review of polycrystalline microwave ferrites with specific reference made to the grain size. Fine-grained ferrites and large-grained ferrites as referred to in this article stand for the ferrites with an average grain size of 2 μm or less and those of 100 μm or larger, respectively. Fine-graining of ferrites is one of the state-of-the-arts techniques for obtaining h... View full abstract»

    Contiguous-disk bubble devices are an approach to higher bit density through the use of coarse overlay patterns in manipulating small bubbles to relax device lithography requirements. As a first step towards such an objective, a fully processed chip using ion-implanted devices has been tested, showing the feasibility of all required memory functions with 5-μm bubbles and 25-μm period ove...

    An analytical expression is derived that describes the response of a magnetic read head of finite width to a magnetized track of finite width shifted in the lateral direction. With this expression the side fringing response and crosstalk from adjacent tracks are calculated and a number of results is presented. View full abstract»

    RF sputter deposited amorphous Co-Gd-Mo thin films have previously been shown to be potential materials for bubble device applications. However, the operation of a bubble device over a realistic temperature range requires materials with magnetic properties which are relatively temperature insensitive. An assessment of the temperature dependence of the magnetic properties of amorphous Co-Gd-Mo film... View full abstract»

  • Chevron detector design study

    Results obtained in a design study which has attempted to optimize the detector chevron and interconneetion geometry are reported. The detector waveform with interconnections between chevrons placed at alternating ends of the chevrons is redundant, with the second half cycle largely repetitious of the first as the domain traverses the detector. The present designs attempt to select the first half ... View full abstract»

  • Induction heating for case hardening applications

    It is observed that the equations describing induction heating in ferromagnetic materials are rather nonlinear. Although the thermal properties are nonlinear, the greatest nonlinearity arises from the ferromagnetic behavior of the material. A way of circumventing this difficulty while retaining the important magnetization curve is presented. A numerical solution accounting for temperature variatio... View full abstract»

    The design of a true swap gate suitable for incorporation into magnetic bubble memory chips with 16-μm to 18-μm circuit periods is reported. The swap operation is true in that the outcoming bubble takes the position vacated by the ingoing bubble, as well as vice versa. Swap gates of this design have been operated successfully at temperatures from 0°C to 70°C, and frequencies up... View full abstract»
