Abstract
The spectrum of standing spin waves is investigated in nanocrystalline Fe f ilms prepared by the pulsed plasma-spraying method. The dispersion relation of these waves is determined in the wave-vector range (0.2-3.2) x 10(6) cm (-1) and is found to be affected by spatial magnetization fluctuations 100 Angstrom in size. These fluctuations are supported as being due to the inho mogeneous distribution of C atoms in the atomic structure of nanocrystallin e Fe films. (C) 2001 MAIK "Nauka/Interperiodica".
