【 摘 要 】

Dielectric permittivity and nuclear diffuse scattering were measured on a single crystal of relaxor magnet LuFeCoO4having the triangular lattice. The dielectric constant with the electric field applied in the c-plane is much larger than that with the electric field applied along the c-axis. We found that the polar nanoregion (PNR) has the anisotropy, and that the strong coupling between PNR and magnetic ordering exists.
