摘要：

Dielectric polarization P (parallel to[110]) of a single crystal of a triangular lattice antiferromagnet CuFeO2 has been measured by pyroelectric technique in pulsed high magnetic fields up to 43 T applied along the [001] direction. Among the five phases successively appeared in magnetic fields, a finite P is observed only in the non-colinear incommensurate (5-sublattice like) phase. The present results indicate that no inversion symmetry breaking occurs in the 4th field-induced phase where a non-colinear spin structure is expected.
