摘要：

A new compound, CaAl4Fe8O19, was synthesized for the first time and characterized by X-ray diffraction. It was found to have a hexagonal magnetoplumbite structure with lattice parameters a = 5.83 angstrom and c = 22.14 angstrom. The electrical studies showed that the compound was a semiconductor with energy of activation q = 0.86 eV. The magnetic susceptibility was studied in the temperature range 300 K to 850 K, in which the compound was paramagnetic with a Curie molar constant of 31.03.
