| Abstract: | A new vanadate PbCo2V2O8 was obtained through the study of PbO-CoO-V2O5 ternary system. The crystal structure was determined by Rietveld method, indicating that PbCo2V2O8 has a tetragonal structure of space group I41cd with a spiral chain along the c-axis. Magnetic properties of the titled compound were investigated by means of susceptibility, magnetization, and heat capacity measurements. The results show that PbCo2V2O8 is a quasi-one-dimensional canted antiferromagnet with Neel temperature of ∼4 K, being consistent with its crystal structure. |
