Abstract :
The magnetic and crystallographic properties of LaNi(5-x) Fex samples (1⩽x⩽1.4) have been studied by X-ray diffraction, neutron diffraction, SQUID and Mossbauer spectroscopy. Samples with x⩾1.2 display typical ferromagnetic behavior. The substitution of iron for nickel in LaNi5 increases the unit cell volume and Curie temperature. The majority (>90%) of the Fe atoms appear to occupy the 3g site. Induced Ni magnetic moments at 30 K have been calculated using the bulk magnetization data and iron magnetic moments
