Abstract

We have carried out magnetic ac susceptibility measurements on Au82(Fe1-xCrx)18 having x = 0, 0.05, 0.1, 0.2, 0.3 and 0.4. It is found that the system retains its reentrant spin glass character below x = 0.2 and then slowly emerges into a spin glass system as a result of competing ferro- and antiferro-magnetic exchange interactions.
