Magnetic susceptibility and neutron diffraction measurements were made on a high purity, polycrystalline sample of ..cap alpha..-phase /sup 242/Pu. The susceptibility results show the existence of weak ferromagnetism below 50/sup 0/K. This suggests that the ..cap alpha..-phase is antiferromagnetic, the observed ferromagnetic moment (9.5 x 10/sup -4/ emu per gram of sample at 4.35/sup 0/K) originating within antiferromagnetic domain walls. No evidence for antiferromagnetic ordering was observed in the neutron diffraction study suggesting that the moment per Pu atom is too small to observe with this technique.
