Abstract
We report on high magnetic field magnetization, magnetic torque, specific-heat, and 51V NMR measurements on Bi4 Cu 3 V2 O14 single crystals, which display a characteristic chain structure along the crystallographic a axis. The system undergoes a magnetic phase transition below 5.5 K. For the magnetic field H||a, the data reveal a metamagnetic transition from an antiferromagnetic (AFM) to a weak-ferromagnetic (WFM) state at Hc ≃7.6T. Based on our results, the low-temperature magnetic phase diagram is determined. Furthermore, the magnetization measurements along with the NMR results suggest that the weak ferromagnetism along the a axis is possibly due to a canted AFM spin structure with two distinct magnetic sublattices.
