title: Intrinsic magnetic properties of single-phase Mn(1+x)Ga (0<x<1) alloys.
abstract: Magnetization measurements have been carried out on a series of carefully prepared single-phase Mn(1+x)Ga (0<x<1) alloys. The saturation magnetization Ms, measured at 5 K, has a value of 92.0 emu/g for x=0.15. This is the highest value reported in these alloys and is close to the calculated value of 116 emu/g for the stoichiometric compound (x=0). Ms decreases gradually with x and has a value of 60.7 emu/g for x=0.86. This behavior is consistent with the extra Mn atoms occupying Ga sites and coupling antiferromagnetically with the rest of the Mn atoms. The intrinsic magnetic properties of the Mn-Ga alloys indicate their great potential as novel, rare-earth free permanent magnetic materials.
