Abstract:

V-substituted LiMnPO4 has been synthesized by the solid state reaction route. Combined Rietveld refinement of neutron and X-ray data revealed that all vanadium ions are located in the same positions as the phosphorus ions. The magnetic structure of LiMnP0.85V0.15O4 was found to be the same as that described for undoped antiferromagnetic LiMnPO4 (T-N=34.5 K). DC-magnetization measurements were carried out to study the peculiarities of magnetic ordering in LiMnP0.85V0.15O4. An irreversible behavior of DC magnetization was found at magnetic fields less than similar to 2 kOe. It was demonstrated that an increase in the magnitude of the applied field leads to a reduction of the discrepancy between zero-field-cooled and field-cooled processes. These effects were explained by the movement of domain walls and by transition of the system to a monodomain state. The anomaly in the magnetization vs field dependence attributed presumably to the spin-flop transition was observed at similar to 40 kOe. The existence of magnetic inhomogeneity in the paramagnetic phase of LiMnP0.85V0.15O4 was proved by the analysis of the chi{*}T product. It was concluded that the observed changes in chi{*}T are indicative of a competition between ferromagnetic and antiferromagnetic correlations at temperatures slightly exceeding T-N.
