Abstract: Let $(M,g)$ be a closed Riemannian manifold of positive Ricci curvature. Let $f$ be a proper isoparametric function on $M$, and $Γ$ the unique level set of $f$ which is a minimal hypersurface. For any positive integer $k$, and $λ>0$ large enough, we construct a solution of the Allen-Cahn equation $ Δu + λ(u-u^3 ) =0$ which is constant along the level sets of $f$ and has exactly $k$ nodal components. We prove that the nodal components approach the minimal isoparametric hypersurface $Γ$ as $λ\rightarrow \infty$ and the energy is uniformly bounded for all such solutions.
