  • Abstract
    We have investigated the dielectric properties of Gd1-xTbxMnO3 crystals in magnetic fields to clarify the crossover between two distinct ferroelectric phases, GdMnO3-type (first-order displacive) and TbMnO3-type (second-order order-disorder). We have found that the compositional phase boundary between the phases exists around 0.3\n\n\t\t
