Document Type and Number:
Japanese Patent JPH05132312
Kind Code:
A
Abstract:
PURPOSE: To produce an amorphous ferroelectric material applicable for thin film type condenser element, ferroelectric memory, electro-optical device, etc.
CONSTITUTION: An amorphous ferroelectric material comprising a ternary oxide consisting essentially of transition metal oxide (M2O3)-aluminum oxide (Al2O3)- Sr2Nb2O7 type compound A2B2O7 wherein the three-component oxide has an amorphous structure. (M2O3 is at least one selected from oxides of Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Y, Zr, Nb, Mo, Pd, Hf, Ta, W, In and lanthanide series element and A2B2O7 is Sr2Nb2O7 type compound showing ferroelectricity, antiferroelectricity and paraelectricity).
