In this comment on 'First-principles studies on magnetic properties of rocksalt structure MC(M=Ca, Sr, and Ba) under pressure'[Appl. Phys. Lett. 98, 182501 (2011)]" we found that their results of the original paper are from nonconverged calculation with respect to the k-point mesh, because they used too few k-points. This gives meaningless results presented in Fig. 1, 2 and 3 in the paper. We recalculated the correpsonding curves.
