Any unit vector field that is a harmonic map is also a harmonic vector field. The study of harmonic map system is more appropriate on a Hermitian manifold and that results in Hermitian harmonic maps to be useful in studying rigidity of complete Hermitian manifolds.

Harmonic vector fields aren't harmonic maps in general (a unit vector field X: M → S(M) is a harmonic map if and only if X is a harmonic vector field and the additional condition trace g {R(∇. X, X)⋅} = 0 is satisfied, cf. Corollary in Chapter 2 of this monograph or O. Gil-Medrano, []).
