Magnetic and crystallographic properties of LaNi/sub (5-x)/Fe/sub x/

The magnetic and crystallographic properties of LaNi/sub (5-x)/Fe/sub x/ samples (1/spl les/x/spl les/1.4) have been studied by X-ray diffraction, neutron diffraction, SQUID and Mossbauer spectroscopy. Samples with x/spl ges/1.2 display typical ferromagnetic behavior. The substitution of iron for nickel in LaNi/sub 5/ 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.
