Description:
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 .
