    摘要： As a magnetic material for high frequencies provided in a high-frequency circuit component used as a high-frequency nonreciprocal circuit device, for example, a circulator and an isolator, a magnetic material which can be densely sintered at a relatively low temperature and has a reduced ferromagnetic resonance half width is provided. The magnetic material for high frequencies is primarily composed of yttrium iron-based garnet in which Ca substitutes for a part of Y site, and V substitutes for a part of Fe site, and does not substantially contain tetravalent nor pentavalent elements, other than V, or contains about 0.5% by weight or less of oxide of this element, and the ratio of Ca atoms to V atoms, Ca/V, falls within the range of 2.0

    摘要： The materials to be sintered are placed in a deformable container which is in turn placed within a non-deformable treatment module equipped with heating means. The temperature of the container is increased under constant pressure until commencement of sintering. The temperature and pressure of the materials are increased simultaneously until sintering conditions are achieved, then maintained at a level stage for a predetermined period of time. The pressure is then reduced to the normal value while maintaining the temperature. The temperature is finally reduced to the room-temperature value.

    摘要： A method of growing monocrystalline bismuth rare earth iron garnet, either as a single crystal or as an epitaxial layer, from a solution containing composing components of the garnet together with a flux. The flux consists essentially of a mixture of Bi.sub.2 O.sub.3 and RO.sub.2, wherein R is at least one of the elements Si, Ge, Ti, Sn, Zr, Ce and Te, wherein the system Bi.sub.2 O.sub.3 --RO.sub.2 includes a eutectic composition having a eutectic temperature which is below the melting temperature of pure Bi.sub.2 O.sub.3. By using these Bi.sub.2 O.sub.3 --RO.sub.2 fluxes, the monocrystalline garnets produced have lower optical absorption coefficients at, for example 5100 A and 5600 A than similar garnets grown using lead-containing fluxes. Furthermore higher growth rates and higher growth temperatures are possible when using the Bi.sub.2 O.sub.3 --RO.sub.2 fluxes rather than lead-containing fluxes.

    摘要： Partial substitution of small amounts of cobalt may result in a reduction in size of ''''bubble'''' magnetic domains in a variety of canted antiferromagnetic materials exemplified by rare earth orthoferrites. The reduction in domain size is ordinarily accomplished by virtue of a shift in the magnetic reorientation temperature, permitting improved device operation in this temperature region.

    摘要： An arrangement for moving single-wall domains is described which employs an in-plane magnetic field to incline a domain from alignment with an axis of preferred magnetization of the material in which it is moved. As the in-plane field reorients, the orientation of the inclination changes. The changing domain inclination is converted to domain translation along an axis defined by a magnetic overlay in which a permanent magnetic pattern is printed.

    摘要： A device for processing electromagnetic wave energy by converting the wave energy to spin waves and/or elastic waves, the present disclosure being particularly directed to the concept of providing a device made up of a single-crystal material which contains non-uniform material parameters to give graded values of material saturation 4 pi Ms. The material discussed in greatest detail is YIG and the non-uniform material parameters are furnished by doping the YIG with gallium. The graded material parameters in combination with an external magnetic bias field H result in an internal magnetic bias field H. The electromagnetic energy as it enters the material is acted upon in a manner that is influenced greatly by the contour of H. The contour of H in the present disclosure, in turn, is predetermined to present gradations in H which will allow the conversion mentioned and which allow predetermination of the wavenumber k of the magnons and/or phonons thereby formed. Furthermore, the place or space within the crystal at which conversion occurs can be somewhat determined by the profile of H thereby provided.
