A large magnetostriction in an antiperoviskite system, Mn_3XN, is well-known for their large magnetovolume effect. The relation of magnetic transformation and negative thermal expansion was discussed. The contrastive difference of several Mn_3XN system was summarized, and the diversification of the linear thermal expansion with different element replacement was analyzed. It is proposed with a view to practical applications and further experiment.
