Abstract:
Spin-wave resonances have been observed in superlattices arising due to the phase separation and self-organization of charge carriers in Eu$_{0.8}$Ce$_{0.2}$Mn$_2$O$_5$ single crystals. The resonances are found within the $5$–$80$ K temperature range at frequencies close to $30$ GHz. Similar resonances with intensities about an order of magnitude lower are also observed in EuMn$_2$O$_5$. The latter suggests the existence of charge transfer processes between the manganese ions of different valences in EuMn$_2$O$_5$.
