Abstract :

We have investigated the dielectric properties of Gd_1-xTb_xMnO₃ 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
