This article explores the necessary and sufficient conditions for a vector field on the cotangent bundle of a Riemannian manifold to qualify as an m- modified conformal vector field or a Ricci bi-conformal vector field. The analysis employs an adapted frame and concerns the Riemannian extension metric.
