Abstract
The magnetic properties of the La(Fe0.873Co0.007Al0.12)(13) intermetallic c ompound have been studied. The compound is a cluster anti ferromagnet showi ng the metamagnetic transition. The magnetic phase diagram of the compound has been constructed. The temperature dependence of the inverse paramagneti c susceptibility of La(Fe0.873Co0.007Al0.12)(13) obeys the Curie-Weiss law. The large positive paramagnetic Curie point indicates the presence of pred ominantly ferromagnetic exchange interactions. The Neel temperature can be considered as the temperature of the ferromagnetic ordering of the Fe magne tic moments in clusters coupled antiferromagnetically. (C) 2001 Elsevier Sc ience B.V.
