Title: Spin-Wave Resonance in Ge : Mn Thin Films with Percolation Magnetic Ordering

Abstract

The mechanism of excitation and propagation of spin waves in Ge: Mn thin films with different nominal manganese concentrations (2, 4, and 8 at % Mn) with percolation magnetic ordering is explored. Concentration dependencies of Curie temperature T{sub C}(n) and spin wave rigidity D(n) are determined, which enables to find the index of correlation distance. An exotic percolation magnetic state of samples of Ge: Mn thin films is confirmed by rectifying experimental dependences D(n) and D/T{sub C}(n) in coordinates accepted in the percolation theory.
