When measuring hysteresis property with bismuth stratified structural ferroelectric crystal and its production manner

摘要

PPROBLEM TO BE SOLVED: To provide a bismuth layered structural ferroelectric crystal which has small coercive electric field Ec and large residual polarization Pr; and to provide its producing method, and an electronic device using the same. PSOLUTION: In the bismuth-containing layered structural ferroelectric crystal, the residual polarization Pr(μC/cmSP2/SP) and the coercive electric field Ec(kV/cm) satisfy Ec≤35 and 1Pr/Ec when the hysteresis characteristics of the crystal are measured at 25°C.
