在1.3 ~ 15 K温度范围内，利用40 T脉冲磁场对UCu 5多晶进行了磁化研究，得到了精确的磁化过程和磁相图。高场测量揭示了TN以下的六步磁化过程。所有这些状态的起源和自旋结构现在还不清楚，但是通过考虑在DyAg晶体中观察到的四极有序自旋系统中的场诱导自旋翻转，可以理解这些转变的轮廓。
Magnetization of UCu5polycrystal is investigated using a pulsed magnetic field up to 40 T with temperatures ranging from 1.3 to 15 K to obtain the precise magnetization process and magnetic phase diagram. High field measurement reveals a six-step magnetization process belowTN. The origin and spin structures of all of these states are not clear now, but an outline of these transitions may be understood by considering the field induced spin flips in a quadrupole ordered spin system as observed in the DyAg crystal.
