    Bubble propagation margins are found to be affected by heat treatment in ion-implanted contiguous-disk devices fabricated on liquid-phase epitaxial (LPE) grown double-layer garnet films which support 1-μm bubbles. When an optical reflector is deposited directly on the driving layer interfacial diffusion takes place, and this raises the coercivity of the implanted layer, which in turn causes a...

    A method is presented for estimating the number of domain walls in grain-oriented 3% Si-Fe tape wound cores under sinusoidal flux conditions by extending the method developed in a study of the dynamic behavior of 50% Ni-Fe square-loop cores. The results show that the number of domain walls increases approximately with exciting frequency asf^{0.4 sim 0.5}. The calculated eddy current los... View full abstract»

    Almost all commercial magnetic recording tapes are manufactured employing a polyester urethane elastomer as the oxide binder and also as the backcoat binder on backcoated tapes. For temperature excursions encountered for ordinary tape use and storage, polyester urethanes as a general class of materials are typically susceptible to environmental degradation by hydrolysis: a chemical reaction betwee...

    The increase of the shielding factor due to shaking was measured in a scale model for a magnetically shielded room. The increase was found to be 7 dB for a single-layer square cylinder biased by the Earth's magnetic field. The shielding factor of a large-volume three-layer Mumetal®room was estimated to increase by a factor of 30, thus confirming the feasibility of shaking in magnet... View full abstract»

    A numerical model for two-dimensional magnetic field problems called the graph-theoretic field model is presented. The theoretical framework of the model places the finite difference and Finite element method in a unifying perspective and brings the solution of magnetic field problems into the well-proven realm of computer-aided design of discrete physical systems. The field distribution in a tran... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (328 KB)

    A conventional magnetic bubble memory with a 6-μm period and submicron details has been made. The memory is an 8-kbit shift register single-mask design with field access NiFe propagation elements. The transfer gates and detector area have an 8-μm period, while the major part of the storage loop has an enhanced density with a 6-μm period. The processing is done with a 1:1 electron im...
