FERROELECTRIC MATERIAL, METHOD OF PRODUCING FERROELECTRIC MATERIAL, AND FERROELECTRIC DEVICE |
摘要 |
Provided are a ferroelectric material having good ferroelectricity and good insulation property, and a ferroelectric device using the ferroelectric material. In the present invention, the ferroelectric material includes a metal oxide having a perovskite-type crystal structure, in which: the metal oxide contains bismuth ferrite whose iron is substituted by manganese, and at least one of a copper oxide and a nickel oxide; the bismuth ferrite is substituted by manganese at a substitution ratio of 0.5 at. % or more to 20 at. % or less with respect to a total amount of iron and manganese; and at least one of the copper oxide and the nickel oxide is added in an amount of 0.5 mol % or more to 20 mol % or less with respect to the bismuth ferrite whose iron is substituted by manganese.
