The temperature dependence of magnetic susceptibility and magnetization of metastable C14-RMn_2 (R=Y, Gd, Tb, Dy and Yb), synthesized at high pressures, has been measured. YMn_2 is an itinerant paramagnet over the whole range of temperatures. GdMn_2, TbMn_2 and DyMn_2 are ferromagnetic at low temperatures, while their susceptibilities beyond T_c obey the Curie-Weiss law. YbMn_2 is a paramagnet down to 4.2 K whose susceptibility suggests antiferromagnetic interactions. These magnetic properties are discussed together with those of other stable C14-RMn_2. Similary to stable C14- and C15-RMn_2, the appearance of local magnetic moments of itinerant 3d Mn electrons of C 14-RMn_2 at low temperatures are determined by the Mn-Mn distance. The Mn atom has a magnetic moment for light rare earths, whereas no moment for heavy rare earths. The critical substance for the onset of Mn moments is TbMn_2.
