Abstract

PbOCu(SeO)(NO)(OH) was synthesized by means of a replacement of (OH) groups for F ions of PbOCu(SeO)(NO)F, showing a transformation of kagomé and breathing kagomé lattices. Such a replacement did not change their intralayer ferromagnetic interactions and interlayer antiferromagnetic (AFM) interactions but slightly affected the Néel temperature and critical field, where PbOCu(SeO)(NO)(OH) possesses an AFM ordering at = 29.3 K, and a field-induced metamagnetic transition can occur at 2 K while a critical magnetic field of 1.45 T is applied.

摘要

通过用(OH)基团取代PbOCu(SeO)(NO)F中的F离子合成了PbOCu(SeO)(NO)(OH)，其呈现出 Kagomé晶格和呼吸Kagomé晶格的转变。这种取代并没有改变它们的层内铁磁相互作用和层间反铁磁(AFM)相互作用，但对奈尔温度和临界场有轻微影响，其中PbOCu(SeO)(NO)(OH)在 = 29.3 K时具有AFM有序性，在2 K时施加1.45 T的临界磁场可发生场致变磁转变。
