The Crystal Structure and Magnetic Properties of the Synthetic Langbeinite KbaFe₂(PO₄)₃
Powder neutron diffraction data have been used to refine the crystal structure of KBaFe2(PO4)3 at 4.2 K; space group P213, a0 = 9.8732(1) Å. The material is isostructural with the mineral langbeinite, having two crystallographically distinct, octahedrally coordinated Fe3+ ions in the asymmetric unit. Mössbauer effect spectroscopy and magnetic susceptibility measurements show that KBaFe2(PO4)3 orders as an L-type ferrimagnet with 3.9 < TC < 4.2 K. The variation of Hint has been monitored by Mössbauer spectroscopy in the temperature range 1.3 < T < 4.2 K. © 1986.
