Abstract

LaFe_13-xSi_x compounds were found to have two types of crystal structure; the face-centered cubic NaZn₁₃-type (x≤2.4) and the body-centered tetragonal Ce₂Ni₁₇Si₉-type (3.5≤x≤5.0). Nitrogenation has a strong effect on the cubic phase, including a large lattice expansion (6.2 to 10.8 %), an increase of Curie temperature (52 to 80 K) and spontaneous magnetization (~ 10 %). The tetragonal phase, however, was not significantly affected by the nitrogenation.
