μSR study of ferromagnetism in potassium clusters incorporated in zeolite LTA

μSR has been studied for a ferromagnetic sample of K clusters in zeolite LTA as a function of longitudinal field (LF) and temperature. Under weak LF a non-relaxing asymmetry component is produced at low temperatures, whereas at higher temperatures in the paramagnetic state a two-component relaxation...

Description
Summary:	μSR has been studied for a ferromagnetic sample of K clusters in zeolite LTA as a function of longitudinal field (LF) and temperature. Under weak LF a non-relaxing asymmetry component is produced at low temperatures, whereas at higher temperatures in the paramagnetic state a two-component relaxation is clearly observed. The data are successfully explained by assuming two different muon-stopping sites in the cubic antiferromagnet, along with a canting of the spin structure.
