          I am currently working on the lithium transition metal phosphates LiMPO₄ (M = Fe, Ni, Co, Cu). Single crystals of LiNiPO₄, LiFePO₄ and LiCuPO₄ were grown by flux method or hydrothermal methods. The magnetic phase transitions and magnetic properties of pure LiNiPO4, LiNiPO4 doped with different iron concentration were studied by SQUID and Neutron diffraction. My previous interests also include recrystallization kinetics, particularly the effects of particles and process parameters in directional recrystallization, and the morphology evolution in diffusion controlled direction solidification process.

• Magnetic phase transitions and single crystal growth of LiNiPO₄, LiFePO₄, LiCuPO₄, and LiNiPO4 doped with Fe³⁺
• Neutron scattering and spin-wave dispersion in LiNiPO₄, LiFePO₄, LiCuPO₄, and LiNiPO4 doped with Fe³⁺
• Using Li(M_1-x, R_x)PO4 (M = Ni, Co, Fe; R - rare earth elements) as high potential cathodes for Lithium-ion rechargeable batteries.
