PIEZOELECTRIC MATERIAL AND DEVICES USING THE SAME |
| 摘要 |
<p>Provided is a Bi-based piezoelectric material having good piezoelectric properties. The piezoelectric material includes a perovskite-type metal oxide represented by the following general formula (1): Ax(ZnjTi(1-j))l(MgkTi(1-k))mMnO3General formula (1) where: A represents a Bi element, or one or more kinds of elements selected from the group consisting of trivalent metal elements and containing at least a Bi element; M represents at least one kind of an element selected from the group consisting of Fe, Al, Sc, Mn, Y, Ga, and Yb; and 0.9@x@1.25, 0.4@j@0.6, 0.4@k@0.6, 0.09@l@0.49, 0.19@m@0.64, 0.13@n@0.48, and l+m+n=1 are satisfied.</p> |
