Converse Magnetoelectric effect in a Room Temperature Multiferroic Pb(Zr0.53 Ti0.47)1-x(Fe0.5Ta0.5)xO3 Ceramic System

We have measured magnetoelectric coefficients by dynamic method in a ball-milled single-phase ceramic material Pb(Zr0.53Ti0.47)1-X(Fe0.5Ta0.5)XO3, [PZTFT], which exhibited multiferroic properties at room temperature for 0.1≤X≤ 0.4 compositions. The room temperature ferroelectric phase showed square hysteresis with maximum remanent polarization as 16μC/cm, saturation polarization as 25μC/cm and no significant change in coercive field (~15kV/cm) for all compositions. Moreover, the materials exhibitted high dielectric constant and very low dielectric loss (~2%). The magnetic properties are also well behaved, with maximum saturation magnetization as ~0.1e.m.u/g and the remanent magnetization as ~0.07emu/g. However, for practical applications in a multifunctional device, only the existence of multiferroic orders at room temperature is not enough, of most importance is to require a strong coupling interaction between the ferroic orders. Experimental studies for in-plane longitudinal and transverse direct magnetoelectric (ME) coefficient are presented. Abstract #2828, Honolulu PRiME 2012, © 2012 The Electrochemical Society
