Dielectric properties of PIN-PT ceramics under compressive stress
Lead indium niobate, Pb(In1/2Nb1/2)O3 or (PIN), is an interesting ferroelectric material, because it can be changed from a disordered state to ordered state by long-time thermal annealing. However, the temperature related to the maximum dielectric constant (Tmax) of PIN in relaxor phase is low (at 1...

Lead indium niobate, Pb(In1/2Nb1/2)O3 or (PIN), is an interesting ferroelectric material, because it can be changed from a disordered state to ordered state by long-time thermal annealing.
