Crystal structure and magnetic properties of Pb_2Ni(PO _4)_2

摘要

A new NiO-based material Pb_2Ni(PO_4)_2 was obtained by a conventional solid-state reaction in air. The crystal structure exhibits both corner- and edge-sharing {Ni-O-P} bonds in the system. Magnetic properties were investigated by means of magnetic susceptibility, magnetization, and heat capacity measurements. The results show a typical three-dimensional antiferromagnetic ordering below ～4 K and a field-induced spin-flop transition below the Néel temperature.
