摘要：

We have studied the crystal structure, magnetic properties, and dielectric properties of Ti-doped hexagonal YMnO3 composed of a Mn triangular lattice with trimerization. It was found that a structural phase transition occurring in YMn1-xTixO3 around x=0.2, which is correlated with a suppression of Mn trimerization by Ti doping, has a substantial effect on the magnetic and dielectric properties of this series of compounds. This correlation between the crystal structure and magnetic and dielectric properties indicates that Mn trimerization plays an important role for the large magnetodielectric coupling unique to hexagonal RMnO3.
