ABSTRACT REFERENCES (29) S. V. Vasiliev Donetsk Institute for Physics and Engineering named after O.O. Galkin, 72 R. Luxemburg Street, Donetsk, 83114, Ukraine V. V. Kruglyak School of Physics, University of Exeter, Stocker Road, Exeter, EX4 4QL, United Kingdom M. L. Sokolovskii Donetsk National University, 24 Universitetskaya Street, Donetsk, 83055, Ukraine A. N. Kuchko Institute of Magnetism, 36-b Vernadskogo Boulevard, Kyiv, 03142, Ukraine We have investigated scattering of exchange spin waves by a model nonuniformity of the effective magnetic field. In particular, certain profiles of the nonuniformity are characterized by a total transmission of the spin wave intensity while inducing large shifts to the phase of transmitted spin waves. These properties are discussed in the context of potential application within a spin wave logic device-a spin wave interferometer containing such a nonuniformity in one of its branches. We demonstrate limitations imposed upon the size and the speed of operation of such a device by a requirement that it be controlled by an external uniform magnetic field. ©2007 American Institute of Physics History:Received 23 February 2007; accepted 9 April 2007; published 14 June 2007 Permalink:
