A new magnetic compound in the Mn–Li–N system was synthesized at GPa-order pressure. This compound had a body-centered-tetragonal (bct) structure (space group: I4/mmm, No. 139) with lattice parameters a = 0.29186 nm and c = 0.39108 nm. The compound composition ratio was Mn:N = 2:1. The saturation magnetization and coercivity of a sample synthesized under 5 GPa at 1100℃ for 2 h were 17.73 A∙m2/kg and 310.7 kA/m, respectively.
