我们测量了具有两个连续的反铁磁转变温度TN 1 =36和TN 2 =32 K，有序矩为0.96 μ B /Np的超硫反铁磁体NpRhGa 5的高场磁化强度.当磁场沿着四方晶系结构[100]方向的易磁化轴时，磁化强度在Hc =26 T处发生变磁转变，并出现一个陡峭的台阶，在Hs =38 T以上达到饱和，其值为0.43 μ B /Np.另一方面，H [001]的难磁化轴磁化强度线性增加，并在H s =28 T以上饱和，具有0.44 µ B /Np。并从磁矩重取向和降低的角度对这些磁化曲线进行了讨论。
We have measured the high-field magnetization for a transuranium antiferromagnet NpRhGa 5 with two successive antiferromagnetic transition temperatures of T N1 =36 and T N2 =32 K and an ordered moment of 0.96 µ B /Np. For the magnetic field along the easy-axis of the [100] direction of the tetragonal structure, the magnetization indicates a metamagnetic transition at H c =26 T with a sharp step and saturates above H s =38 T, with 0.43 µ B /Np. On the other hand, the hard-axis magnetization for H ∥[001] increases linearly and saturates above H s =28 T, with 0.44 µ B /Np. These magnetization curves were discussed on the basis of reorientation and reduction of the magnetic moment.
