Abstract A new hexaferrite with the composition (Ba,Pb)(Fe,Ti)9O15 was synthesized from lead(II) oxide flux, which lead to the incorporation of Pb2+ into the structure on the barium position. Like other ferrites, its structure can be described as the stacking of characteristic building blocks along [001]. Within the structure, the barium site is mixed occupied with lead. Octahedrally coordinated interstices are filled by iron and titanium in different ratios. Tetrahedra and trigonal bipyramids are solely occupied by iron. Wavelength dispersive X-ray spectroscopy provides the composition Ba0.69(1)Pb0.34(2)Fe7.28(7)Ti1.52(3)O15. Lastly, the compound shows ferrimagnetic behavior with a Curie temperature of TC = 309.3 °C and a strong indication for a magnetic phase transformation to ferromagnetic state at high magnetic field strengths and at temperatures below −123 °C.
