Description
ROFeAs with R=La,Ce,Pr,Sm,Gd are the magnetic mother compounds of the iron pnictide superconductors. We have investigated the magnetic properties and the interplay of iron and rare earth magnetic order in GdOFeAs by means of muon spin relaxation (μ+SR) and 57Fe Moessbauer spectroscopy and compare these to other undoped ROFeAs. We find that the Gd mother compound shows magnetic interaction between the rare earth and the FeAs layers similar to the Ce compound. This results indicate that the rare-earth-FeAs electronic interaction is not crucial for the enhanced TC in these systems.
