| dc.description.abstractEn | A new oxyphosphate, PbFe<sub>3</sub>O(PO<sub>4</sub>)<sub>3</sub>, has been discovered and its structure has been characterized by single-crystal XRD between 293 and 973 K (monoclinic, space group<em>P</em>2<sub>1</sub>/<em>m</em>, <em>a</em> = 7.5826 Å, <em>b</em> = 6.3759 Å, <em>c</em> = 10.4245 Å, <em>β</em> = 99.956°, <em>Z</em> = 2, at r.t.). Direct-current (DC) magnetic susceptibility and specific heat measurements performed on single crystals revealed an unusual sequence of second-order ferromagnetic-like phase transitions at <em>T<sub>c</sub></em><sub>1</sub> = 31.8 K, <em>T<sub>c</sub></em><sub>2</sub> = 23.4 K and <em>T<sub>c</sub></em><sub>3</sub> ≈ 10 K. Alternating-current (AC) magnetic susceptibility measurements suggest glass-like dynamics between ca. 20 K and <em>T<sub>c</sub></em><sub>3</sub>. | |
