摘要合成了具有cu2s2和钙钛矿氧化物交替层状的新型氧化硫化物,并对其进行了表征。sr3cu2fe2o5s2和sr2cumo3s (M =Cr, Fe, In)的钙钛矿氧化物层分别为(feo2)(SrO)(feo2)和(m2 o2)(SrO)(SrO)(m2 o2)。所有的Fe、Cr和In阳离子都呈方锥配位几何。磁测量表明,Sr 2 CuCrO 3s在60k时具有反铁磁有序。
Abstract New layered oxysulfides with alternating Cu 2 S 2 and perovskite oxide layers have been synthesized and characterized. The perovskite oxide layers for Sr 3 Cu 2 Fe 2 O 5 S 2 and Sr 2 Cu M O 3 S ( M =Cr, Fe, In) are (FeO 2 )(SrO)(FeO 2 ) and ( M O 2 )(SrO)(SrO)( M O 2 ), respectively. All Fe, Cr, and In cations are in a square-pyramidal coordination geometry. Magnetic measurement shows an antiferromagnetic ordering at 60 K for Sr 2 CuCrO 3 S.
