“…[18]: M1 -site: 2 Phosphorus atoms +13 metal atoms, M2: 4P +10M and M3: 3P +11M) cannot be invoked to clarify this problem. Nevertheless, these results are in agreement with neutron diffraction experiments [35]. For the isostructural synthetic (Fe,Co) 3 P the same trend for the distribution of Fe and Co was established.…”

A survey is presented on some characteristic features of meteoritic (Fe,Ni) 3 P which is an abundant and important minor phase of most iron meteorites. This mineral (named schreibersite/rhabdite) plays a decisive role during the formation of the so-called Widmanstätten pattern. Different transmission as well as scanning electron microscopic techniques have been applied to get more precise information about the real structure of the phosphide crystals, their chemical composition and the metal distribution across the phoshide/ kamacite interface. X-ray crystal structure determinations have been performed for selected (Fe,Ni) 3 P -cystals from various iron meteorites (Toluca, North Chile, Watson, Orange River, Morasko, Agpalilik, Odessa, Canyon Diablo). These experiments revealed a metal ordering, i.e. for the three non-equivalent metal positions a different substitution of Fe by Ni has been found. The perfection of the brittle (Fe,Ni) 3 P samples differs appreciably and seems to be dependent on the thermal history of each individual meteorite. Moreover, inside Ni-rich rhabdite crystals small monocrystalline inclusions of CrN (carlsbergite) have been detected.

“…[1][2][3][4][5][6][7] Fe 3 P is a ferromagnetic compound with a Curie temperature of 692 K ͑Ref. 5͒ and a saturation magnetization of 1.70 B /Fe atom at room temperature 1,4 and 1.89 B /Fe atom at 10 K. 5 The crystal structure is tetragonal ͑space group I 4 ) with three different Fe sites ͑denoted I, II, and III͒. The combination of a tetragonal structure and the introduction of P produces a large magnetocrystalline anisotropy.…”

“…4 This enables studies of the magnetic properties of one class of isostructural materials with the controlling parameter being the filling of electrons in the valence band. Recently, a detailed experimental and theoretical study of the (Fe 1Ϫx Co x ) 3 P compounds 5 has been published, where it was found that the introduction of Co decreases the magnetic moment in the entire range of solid solution (0ϽxϽ0.37). The Co atoms were found to preferentially substitute Fe on atomic sites III and II.…”

Structural and magnetic properties of (Fe 1Ϫx Mn x ) 3 P compounds have been investigated by means of x-ray and neutron diffraction experiments, magnetization measurements, Mössbauer experiments, and first principles calculations. The Curie temperature of the system decreases linearly and rapidly with increasing Mn content. The zero temperature saturation magnetization, the local magnetic moments, as well as the hyperfine fields on the different metal positions of the system all decrease with increasing Mn content. The theoretical calculations, on the other hand, predict an increasing magnetic moment on the metal positions with increasing Mn content. This apparent discrepancy is discussed in the light of a good agreement between experimental and theoretical results for the Co-substituted sister compounds (Fe 1Ϫx Co x ) 3 P. PHYSICAL

“…From the single-crystal refinements for natural schreibersites (e.g. Doenitz, 1968Doenitz, , 1970Skála and Císařová, 1999, 2001) and magnetic refinement from neutron data for isostructural (Fe 1Àx Co x ) 3 P (Liu et al, 1998) it is known that there is uneven distribution of metallic atoms over three crystallographically non-equivalent sites within the structure. We also attempted to refine site distribution for both types of atoms within the structure; however, the scattering factors are so close that they could not be resolved effectively from the data available.…”

ABSTR ACTThe original description of nickelphosphide from the Butler meteorite [(Ni 1.83 Fe 1.21 ) S3.04 P 0.96 to (Ni 1.71 Fe 1.28 Co 0.01 ) S3.00 P 1.00 ] lacks detailed and accurate powder data À with only 11 observed reflections down to 1.37 Å . Consequently, no crystal structure information for this phase is available. Here we present the crystal structure for a synthetic analogue of the phase found in the Vicenice IID medium octahedrite (with a mean empirical formula of (Ni 1.69 Fe 1.31 ) S3.00 P 1.00 ) and a hypothetical Ni 3 P end-member. Unit-cell dimensions of the synthetic analogue of Ni 1.68 Fe 1.33 P 0.99 composition from individual peak profile fitting of XRD data collected with Cu radiation are a = 9.0168(2) Å , c (8) Å 3 . The space group of the mineral is I4 and Z = 8. The crystal structure refined from powder data by the Rietveld method is consistent with that refined and published for Fe 3 P and Ni 3 P synthetic compounds as well as Fe-dominant schreibersite from single-crystal data. However, because of the similarity of the scattering of iron and nickel, we were not able to refine directly the site occupancies in the synthetic analogue of the nickelphosphide from the Vicenice iron meteorite.
