Abstract
The spin-wave resonance (SWR) spectra have been observed in the (001) orien ted La0.7Mn1.3O3-delta epitaxial films. The spectra consist of a series of well-resolved spin-wave modes clearly seen in the: perpendicular external f ield configuration. It is shown that the spins are completely pinned on bot h sides of the film surface. Based on a study of the SWR spectra the value of the spin-wave exchange constant, D, is found to be 150 meV Angstrom(2). This value of. D correlates well with this one determined for all known unt il now manganites. (C) 2000 no-transfer. Published by Elsevier Science B.V. All rights reserved.
