We have developed a repeating high field pulsed magnet for neutron scattering experiment. We have adopted Ag-Cu alloy which has higher share strength with reasonable electric conductivity. We could succeed to operate it at 27T practically. This is the world record as a magnet for neutron scattering. By using the magnet we have performed a neutron scattering experiment on CsCuC13 to observe a magnetic structural phase transition due to quantum effect in a field.

我们研制了一种用于中子散射实验的高场重复脉冲磁体。我们采用了银铜合金，具有较高的份额强度和合理的导电性。实际上，我们可以成功地在27 T下操作它。这是中子散射磁铁的世界纪录。利用该磁体对CsCuC_（13）进行了中子散射实验，观察到了磁场中量子效应引起的磁结构相变。
