The iron nickel phosphides (Fe,Ni)3P are occurred in iron meteorites in the forms of schreibersite and rhabdite. Schreibersite and rhabdite are formed as a result of heterogeneous and homogeneous nucleation mechanisms, respectively. In the present work variously study of the samples of phosphide extracted from Sikhote-Alin meteorite (group IIB). The results demonstrate the difference of the chemical concentrations and magnetic properties in phospides related to its structure.
