Abstract

X-band magnetic resonance has been used to study a set of Fe/ Ag(001) superlattice (SL) samples with Fe layers only 0.9–5.5 monolayers (ML) thick. The samples (grown by MBE and previously examined by Mossbauer and magnetization techniques) were studied thoughout the 5–300 K range. The SL's with t(Fe) < 3 ML exhibit a marked downturn in their resonance fields below a temperature which decreases with t(Fe) and, simultaneously, the linewidths increase. We suggest that this behavior is due to magnetic relaxation processes in these samples.
