摘要：
Spin-wave resonances have been observed in superlattices arising due to the phase separation and self-organization of charge carriers in Eu0.8Ce0.2Mn2O5 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 EuMn2O5. The latter suggests the existence of charge transfer processes between the manganese ions of different valences in EuMn2O5.
