  An isometric immersion $x:M^n\rightarrow S^{n+p}$ is called Willmore if it is
an extremal submanifold of the Willmore functional: $W(x)=\int_{M^n}
(S-nH^2)^{\frac{n}{2}}dv$, where $S$ is the norm square of the second
fundamental form and $H$ is the mean curvature. Examples of Willmore
submanifolds in the unit sphere are scarce in the literature. The present paper
gives a series of new examples of Willmore submanifolds in the unit sphere via
isoparametric functions of FKM-type.
