Abstract
The spin dynamics of 2-dimensional ferromagnetic monolayers of [MnSb/S b] were studied by the mu+SR method using pulsed sub-surface muons wit h a momentum of 18 - 25 MeV/c. A gradual growth of a static field alon g the mu+ spin below 200 K and a divergent increase of the relaxation rate at around 25 K were observed in the 1 monolayer sample, related t o the critical fluctuations in this magnetic superlattice.
