Abstract
La(FexAl1-x)13 pseudobinary intermetallic compounds, which can be stabilized for 0.46<x<0.92, have been studied by neutron diffraction and Mössbauer spectroscopy. Neutron measurements on an antiferromagnetic x=0.91 sample at 4.2 K reveal a long-range-order antiferromagnetic state, consisting of ferromagnetic clusters, coupled antiferromagnetically. Mössbauer-effect measurements show a drop of the hyperfine field at the Fe nucleus at the ferromagnetic-antiferromagnetic phase boundary x0.88. Both these microscopic measurements indicate a transition from -iron-like ferromagnetism to -iron-like antiferromagnetism due to the extremely high coordination of Fe atoms.
