- Аннотация: Two quaternary phosphide platinides, Eu2Pt7CrP2.80 (I4/mmm, a = 4.0268(3) Å, c = 26.813(3) Å, V = 434.78(8) Å3, Z = 2, R1 = 0.0328, wR2 = 0.0785) and Eu2Pt7FeP3.02 (I4/mmm, a = 4.0359(6) Å, c = 26.641(5) Å, V = 433.94(16) Å3, Z = 2, R1 = 0.0276, wR2 = 0.0741) were synthesized as single crystals by a high-temperature route using metallic fluxes (Pb or Bi), their crystal structures were established from single-crystal X-ray diffraction data and confirmed by elemental analysis. The compounds crystallize in the tetragonal system, and represent heterostructures built from the alternating layers of AuCu3- and CaBe2Ge2-type fragments. Based on the DFT-calculations both compounds are metallic. Chemical bonding analysis reveals a pattern of covalent, metallic and ionic interactions within each compound. Magnetic measurements show both compounds to be ferromagnetic with a high degree of magnetic anisotropy, and reveal an antiferromagnetic exchange between two magnetic sublattices (europium and chromium or iron), which makes such compounds promising objects for use in spintronics.
