Abstract:
PbOCu3(SeO3)2(NO3)(OH) was synthesized by means of a replacement of (OH)- groups for F- ions of PbOCu3(SeO3)2(NO3)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 PbOCu3(SeO3)2(NO3)(OH) possesses an AFM ordering at TN = 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.
