Title: Magnetic and crystallographic properties of LaNi{sub 5{minus}x}Fe{sub x}

Abstract

The magnetic and crystallographic properties of LaNi{sub (5{minus}x)}Fe{sub x} samples (1 {le} x {le} 1.4) have been studied by x-ray diffraction, neutron diffraction, SQUID and Moessbauer spectroscopy. Samples with x {ge} 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.
