It is shown explicitly that the frequencies of small k, infinite-film spin waves follow guide curves, which are simply the dispersion relations for pure magnetostatic modes (exchange constant D = 0) with the internal field H sub i replaced by H sub i + Dk to the 2nd power. A previous result, that the magnetostatic-mode frequencies are independent of the pinning, apart from splitting at crossovers of the guide curves, is a special case of the general result. Two regions of linearity of omega exist as a function of the magnitude k sub f of the wave vector in the plane of the film, but have no practical consequences at present. 8 pp. Ref. (Author)

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
