Pr6Fe13Si crystallizes with La6Co11Ga3-type tetragonal phase (space gr
oup I4/mcm) by annealing the are-melted buttons at some temperatures i
n the range 550-750 degrees C. The Curie temperature of Pr6Fe13Si is 3
98 K, and the compensation temperature is 366 K. The values of spontan
eous magnetization at 1.5 K, 0.3 mu(B)/f.u. The magnetocrystalline ani
sotropy is easy c-axis at room temperature and the anisotropy field is
