Abstract. Inspired by the recent work [HHM03], we prove two stability
results for compact Riemannian manifolds with nonzero parallel spinors.
Our first result says that Ricci flat metrics which also admit nonzero parallel
spinors are stable (in the direction of changes in conformal structures) as
the critical points of the total scalar curvature functional. Our second result,
which is a local version of the first one, shows that any metric of positive
