Description
The first neutron scattering experiments on PuAs and PuSb single crystals are reported. PuAs is found to be a ferromagnet below T/sub c/ = 123 +- 1 K. PuSb develops below T/sub N/ = 85 +- 1 K an incommen- surate ordering and undergoes, at T/sub I/C = 67 K, a first-order transition to a commensurate phase, ferromagnetic in nature. In both compounds, moments are perpendicular to the ferromagnetic (001) planes, their low-temperature value is μ = (0.75 +- 0.1)μ/sub B/, indicating a GAMMA8-type ground state within the Russell-Saunders level scheme. The magnetic phase diagram of PuSb has been determined. The incommensurate phase is suppressed by a small field of 8.5 kOe
