Abstract
A composition for forming a film, comprising a solution of metal compounds in an organic solvent, wherein a molar ratio of metals in said solution is (Sr.sub.1-n R.sub.n):Bi:(Ta.sub.Y Nb.sub.1-Y)=X:Q:2, R is at least one element selected from the group consisting of La, Ce, Pr, Nd, Eu, Sm, Tb, Gd and Er, and 0<n.ltoreq.0.1, 0.4.ltoreq.X<1, 0.ltoreq.Y.ltoreq.1 and 1.5.ltoreq.Q.ltoreq.3.5, can be used to form a ferroelectric film. This ferroelectric film is useful in a ferroelectric capacitor, particularly a ferroelectric capacitor for a non-volatile memory.
