N2 - We measured the high-field magnetization up to 55 T and constructed a magnetic phase diagram for a transuranium antiferromagnet NpRhGa5 with the tetragonal structure. The magnetization at 4.2 K for H ∥ [1 0 0] indicates a sharp metamagnetic transition with a step at Hc = 26 T and saturates above Hs = 38 T, reaching 0.43 μB / Np. An ordered moment of 0.96 μB / Np at zero field, which was determined from the neutron scattering experiment, is found to be reduced to 0.43 μB / Np at Hs, together with an orientation of the magnetic moment from the (0 0 1) plane to the (1 0 0) plane.
